WebSep 15, 2024 · Bellatrix is a bluish main sequence star with the stellar classification B2 V. It has the spectrum of a giant, which is why a number of sources cite the spectral type of a giant, B2 III. Both the Simbad and NED databases give the spectral type B2 V, indicating that the star is still a hydrogen-fusing dwarf. WebIt is based on two sets of parameters: a refined version of the Harvard O-M scale, and a luminosity scale of grades I (for supergiants), II (bright giants), III (normal giants), IV (subgiants), and V (main sequence, or dwarf, …

These ideas are summarized in Table 18.2. We have also ...
WebMain-sequence stars are fusing hydrogen into helium. These nuclear fusion take place deep in the cores of stars. Stars spend about 90% of their lives in this stage. Our Sun is about 5,000 million years into its 10,000 million-year main-sequence.. One of the fundamental forces in the Universe is gravity.It is the force that holds us on Earth.
