We will define a high-mass star as one with a final mass of greater than 10 M⊙. On the main sequence this group would include stars of spectral type O, B0, and B1. Although stars in this mass range are few in number compared with low-mass stars, they are extremely important with regard to galactic chemical evolution and the physics of the interstellar ...

One of the most durable problems in all of astrophysics is how stars are formed. Since the time of LaPlace astromomers have postulated numerous scenerios, but to the present this problem has resisted solution. This is especially true for massive stars. Massive star formation (MSF) has received much less observational and theoretical attention than low ...

I.Introduction The formation process of massive O and B stars is arguably the least understood of all stars. The major observational and theoretical emphasis has been concentrated on low mass star formation during the past decade for a varitey of reasons, among which are: it is a more tractable problem than massive star formation and it is well matched

Massive Stars: Setting the Stage
Space Science Reviews, 1993The paper gives a summary of the situation mid-1993 of theory and observations regarding massive stars. I describe: stellar mass loss and its implications, pre-main-sequence evolution, the main sequence, problems of atmospheric instability, Luminous Blue Supergiants, Yellow Hyper-giants, Wolf—Rayet stars and supernovae.

Since the generation of the first stars (see Sect. 9.6) massive star-formation has been the major driver in the evolution of the universe as we know it today. Massive stars are the factories that produce elements up to iron during their lifetimes and enrich the ISM with heavy trace elements during their supernova phases. Furthermore their UV radiation,

Properties of massive star evolution
Space Science Reviews, 1994New models of massive stars have been calculated as a part of a project aimed at the construction of an extended grid of stellar tracks for several metallicities, covering all the main evolutionary phases of low, intermediate and massive stars, with updated physics.
