    Cambridge Core - International Astronomical Union Colloquium - Volume -. Luminous Blue Variables, Cool Hypergiants, and Supernova Impostors: The Role of Episodic Mass LossAuthor: A. Mehner, W.J. de Wit, D. Baade, H.M.J. Boffin, K. Davidson, J. Groh, R.M. Humphreys, C. Martayan.

      The researchers’ paper, “Luminous Blue Variable Outbursts from the Variations of Helium Opacity,” is the cover story in the journal Nature. Of particular interest to the researchers are the stars’ mass loss rates, which are significant compared to those of less massive stars. Luminous intensity, the quantity of visible light that is emitted in unit time per unit solid angle. The unit for the quantity of light flowing from a source in any one second (the luminous power, or luminous flux) is called the lumen. The lumen is evaluated with reference to visual sensation. The.

      Russian astronomers have identified three new luminous blue variable (LBV) candidates in the star-forming galaxy NGC While one of the .   The strong mass loss of Luminous Blue Variables (LBVs) is thought to play a critical role in the evolution of massive stars, but the physics of their instability and their place in the.

Physics of Luminous Blue Variables We can imagine, at least, that the study of Luminous Blue Variable stars began as the official court astrophysicists of Eridu speculated about a new years ago first-magnitude star which persisted in their southern sky for several years.2 After that the topic languished for a while, but now it has been.

Described are the specific characteristics, the evolutionary state and what they are connected to other phases and types of massive stars.

The topics addressed include: characteristics and role of LBVs in the upper H-R diagram, evolutionary status and instability mechanism of LBVs, evolutionary diagnostics of LBV spectra and systems in the LMC, distribution of LBV types, age of LBV candidates from their stellar and nebular environment, a UV.

The luminous blue variable (LBV) phase of evolution, punctuated by eruptive mass loss, is thought to be important in the mass-loss evolution of massive stars [1,2].However, the physics of their instability and its influence on stellar evolution have been challenging to understand by: 7.

(Eds.) Free Preview. Some of the most luminous stars have sporadic, violent mass-loss events whose cuases are not understood.

These evolved hot stars are called Luminous Blue Variables (LBV's), and their instability may shape the appearance of the upper HR diagram.
