Luminous blue variables (LBVs) are rare, massive, evolved stars that show unpredictable and sometimes dramatic variations in their spectra and brightness. They are also known as S …

2020年9月7日 · Luminous Blue Variables are massive evolved stars, here we introduce this outstanding class of objects. Described are the specific characteristics, the evolutionary state …

物理图像 光度 典型的LBV的本征光度非常高，典型的热星等通常大于-9.5，对应大约 10 6 L ⊙。 但也存在部分低光度的LBV（less luminous LBV）， M b o l ≈ − 8 或 − 9。 两种LBV的起源以 …

2010年10月11日 · We study the long term, S Dor-type variability and the present hot phase of the LBV star GR290 (Romano's Star) in M33 in order to investigate possible links between the …

Luminous Blue Variables are massive evolved stars, here we introduce this outstanding class of objects. Described are the specific characteristics, the evolutionary state and what they are …

2017年9月18日 · Luminous blue variables (LBVs) had long been considered massive stars in transition to the Wolf–Rayet (WR) phase, so their identification as progenitors of some peculiar …

Luminous Blue Variable Stars, also known as LBVs, are a class of massive supergiants that are the most luminous stars in a galaxy. They exhibit significant variations in luminosity and …

In addition the short duration of the LBV phase makes it even harder to catch and identify a star as LBV. We summarize here what is known so far, give an overview of the LBV population and …

Luminous Blue Variable (LBV) Stars are very massive, hot supergiants. They are unstable and variable, with irregular mass ejections. A mass loss episode increases the brightness. A cool …

2011年4月30日 · The star has revealed an absolute maximum of visual brightness (1992-1994, high/cold state) and an absolute minimum (2007-2008, low/hot state). The variability of the …
