About What Is Rigel’s Surface Temperature

About What Is Rigel’s Surface Temperature – Rigel is a bright blue star in the constellation Orion. It has the name Bayer β Orionis, Latinized to Beta Orionis and abbreviated Beta Ori or β Ori. Rigel is the brightest and most massive part – with the name – of a star system of four or more stars that appear to the naked eye as a blue-white halo of light. This system is at a distance of 860 light-years (260 pc) from the Sun.

A star of type B8Ia, known as Rigel is anywhere from 61,500 to 363,000 times as massive as the Sun and 18 to 24 times as massive, depending on the method and assumptions used. . More than seventy times that of the Sun, its surface temperature is 12,100 K. Due to its stellar atmosphere, Rigel’s mass loss is estimated to be t million times that of the Sun. Seven to nine million years old, Rigel has exhausted its nuclear fuel and expanded and cooled to become a superhuman. It is thought to be a type II supernova, leaving a neutron star or black hole as the final remnant, depending on the initial mass of the star.

About What Is Rigel’s Surface Temperature

Rigel varies in brightness, from 0.05 to 0.18 magnitude. It is classified as an Alpha Cygni variable due to its high intensity and availability of bright contrast, as well as its characteristic shape. Internal variation is caused by friction in an inert atmosphere. Rigel is the seventh brightest star in the night sky and the brightest star in the Trinity, although it sometimes outstrips Betelgeuse, which differs from the larger area.

A triple star system is separated from Rigel by an angle of 9.5 arcsec. It has a magnitude of 6.7 and is 1/400th as bright as Rigel. There are two stars in the system that can be seen by large telescopes, and the brightest of the two is a spectroscopic binary. These three stars are all blue-white stars, each three to four times the mass of the Sun. Rigel and the triple system surround a common fence and span 24,000 years. The inner stars of the triple system orbit each other every ten days, and the outer star orbits the inner binary every 63 years. A faint star, separated from Rigel and the others by about a minute of arc, may belong to the same star system.

In 2016, the International Astronomical Union (IAU) added the name “Rigel” to the IAU Catalog of Star Names.

According to the IAU, this proper name refers to the first phase A in the Rigel system. In early astronomy books, the system was variously listed as H II 33, Σ 668, β 555, or ADS 3823.

Rigel’s designation β Orionis (Related to Beta Orionis) was coined by Johann Bayer in 1603. The symbol “beta” is given to the second brightest star in each constellation, but it is almost moon of Rigel in α Orionis (Betelgeuse) .

Astronomer James B. Kaler said that Rigel was identified by Bayer in a rare moment when the variable star Betelgeuse appeared, because the latter star is “alpha” and Rigel is the code “beta”.

Rigel and Betelgeuse were thought to belong to the first large class, and in Trinity it is believed that the stars of each class were arranged from north to south.

Rigel is included in the Geral Catalog of Variable Stars, but since Bayer has it, it does not have any variable stars.

What Are Blue Supergiant Stars?

Rigel has many other star symbols from various catalogs, including Flamsteed symbol 19 Orionis (19 Ori), Bright Star Catalog try HR 1713, and Hry Draper catalog number HD 34085. These symbols can be found in scientific literature.

It is usually the seventh brightest star in the celestial sphere, excluding the Sun, although it is sometimes smaller than Betelgeuse.

Ending each year between midnight on December 12 and 9:00 PM on January 24, Rigel can be seen on winter evenings in the Northern Hemisphere and summer evenings in the Southern Hemisphere. .

It is also the first Triune star to appear in most of the Hemisphere. The star is a corner of the “winter hexagon”, an asterism that includes Aldebaran, Capella, Pollux, Procyon and Sirius. Rigel is a popular navigational star, easy to find and visible in all oceans of the world (except the area north of the 82nd parallel north).

Types Of Stars

The entire spectrum is typical of a late B-class star, with strong absorption lines from the Hydrog Balmer series to neutral helium lines and some heavy elements such as oxygen, calcium and magnesium.

The luminosity class of B8 stars is determined from the intensity and narrowness of the hydrog spectrum lines, and Rigel is the brightest class Ia star.

Differences in the spectrum have resulted in different classes being assigned to Rigel, such as B8 Ia, B8 Iab and B8 Iae.

As early as 1888, Rigel’s radial helioctric velocity, estimated from the Doppler shifts of its lines of sight, was variable. It will be verified and translated by an enthusiastic partner with a duration of 22 days.

In 1933, the Hα line in the Rigel spectrum was thought to be weak, shifted 0.1 nm to a shorter wavelength, while the emission peak was narrow at about 1.5 nm toward the wavelength. length of main input line.

This is now known as the symbol P Cygni after a star that strongly exhibits this feature in its orbit. It refers to the simultaneous emission from the dse gas close to the star and absorption from the spherical objects extending away from the star.

The unusual shape of the Hα line appears to be different. About a third of the time it’s just an input line. About a quarter of the time the peak is a double line, that is, an emission line and an emission core, or an emission line and an absorption core. About a quarter of the time he has a P Cygni sign; The line usually has an inverted P Cygni signal, and the transmission part is on the short wave side of the line. The pure emission Hα line is small.

Page changes are defined as differences in the amount and speed of material coming from the star. Very high flow rates have been determined, and it is difficult, and the event is very difficult. The overall picture is one of large circular structures that appear in the photo of the planet, driven by magnetic fields.

Rigel has been known to vary in brightness since at least the 1930s. The low intensity of Rigel’s brightness variation requires an electronic photo or CCD imager to be seen reliably. There is no visible moment of this brilliant contrast. Observations over 18 nights in 1984 showed variations in red, blue, and yellow wavelengths of up to 0.13 magnitude on time scales ranging from a few hours to a few days, but no clear period. . Rigel’s color index is different, but this is not directly related to its brightness differences.

From an analysis of the Hipparcos radiograph, Rigel is found to belong to the Alpha Cygni class of variable stars,

In these types of pulses, the “e” indicates that it shows emission lines in its spectrum, while the “p” means an unspecified spectrum. Alpha Cygni type variables are considered neutral

Rigel was added to the Geral Catalog of Variable Stars in the list of 74 variable stars based on the Hipparcos description,

Characteristics Of Stars

Rigel was observed by the Canadian MOST satellite for about 28 days in 2009. Variations in the mass were observed, and the changes in flow reflect the seasonal patterns. long.

From observations of the spectral Hα line, the Rigel mass-loss rate due to the stellar wind is estimated to be (1.5± 0.4)x 10−7 solar masses per year (M☉/yr)—approx. the t million times the mass-loss. Articles to follow.

Additional optical and K-band infrared spectroscopic observations, as well as VLTI interferometry, were performed from 2006 to 2010. Analysis of the Hα and Hγ line spectra and measurements of the emission regions line shows that the composition of Rigel’s stellar atmosphere is very different. strength Structures of the wrist and hand were also found in the air. Calculations of the mass loss from the Hγ line give (9.4± 0.9)× 10−7 M☉/yr in 2006–7 and (7.6± 1.1)× 10−7 M☉/yr in 2009– 10. Calculations with the Hα line give lower results, about 1.5× 10−7 M☉/year. The final wind speed is 300 km/s.
