WebSep 7, 2024 · Star type Zubeneschamali is a hot blue hydrogen-fusing star of the spectral type B8 V. It has a mass 3.5 times that of the Sun and a radius 4.9 times solar. The radius is derived from the star’s angular diameter, measured at 0.801 milliarcseconds in 2009. With an effective temperature of 12,300 K, Zubeneschamali shines with 130 solar luminosities. WebThe luminosity class for B8 stars is estimated from the strength and narrowness of the hydrogen spectral lines, and Rigel is assigned to the bright supergiant class Ia. [41] Variations in the spectrum have resulted in the assignment of different classes to Rigel, such as B8 Ia, B8 Iab, and B8 Iae.

Stellar classes typically have three elements: a letter (O-B-A-F-G-K-M), an Arabic number between 0 and 9, and a Roman number between I and VII (or a zero). The letter indicates the spectral class, which is determined based on the star’s effective temperature. dodge dealership lakeport ca
