  2. Giant star - Wikipedia

    en.wikipedia.org/wiki/Giant_star

    Giant stars have radii up to a few hundred times the Sun and luminosities over 10 times that of the Sun. Stars still more luminous than giants are referred to as supergiants and hypergiants. A hot, luminous main-sequence star may also be referred to as a giant, but any main-sequence star is properly called a dwarf, regardless of how large and ...

  6. Alpha Lupi - Wikipedia

    en.wikipedia.org/wiki/Alpha_Lupi

    Alpha Lupi is a giant star with a stellar classification of B1.5 III. [4] It has about ten times the mass of the Sun [ 7 ] yet is radiating 18,000 times the Sun's luminosity. The outer atmosphere has an effective temperature of 24,550 K, [ 8 ] which gives it the blue-white glow of a B-type star .

  8. Rifamycin - Wikipedia

    en.wikipedia.org/wiki/Rifamycin

    It contains genes rifG through rifN, which were shown to biosynthesize AHBA.[10] RifK, rifL, rifM, and rifN are believed to act as transaminases in order to form the AHBA precursor kanosamine. [13] [14] "RifH" encodes aminoDAHP synthase that catalyzes the condensation between 1-deoxy-1-imino-d-erythrose 4-phosphate and phosphoenolpyruvate. [15]

    en.wikipedia.org/wiki/Pi1_Gruis

    A visual band light curve for π 1 Gruis, adapted from Mayer et al. (2014) [4] π 1 Gruis is an asymptotic giant branch (AGB) star of spectral type S5. It is one of the brightest members of a class of stars known as S stars. It is also a semi-regular variable star ranging from apparent magnitude 5.3 to 7.0 over a period of 198.8 days. [8]
