... Dr. Stella Kafka . Thursday, Dec 10, 2015 at 8:00 PM . Type I Supernovae are massive stellar explosions that result from an interaction between a white dwarf and a companion whose mass it accrues in a close binary system. When the white dwarf’s mass reaches 1.4 that of the sun, the supernova occurs. ...

... The available observational data on masses and/or luminosities of binary components and the current models for different chemical compositions of Pop I stars were used to improve the mass-luminosity relation for stars of moderate masses. ... This technique was also applied to decompose the low-mass components of several stars suspected to be unresolved binaries. ... The method is based on the minimum determination technique applied to functions of several variables covering a limited range of values...

STAR FORMATION EFFICIENCY AND GRAVITATIONAL STABILITY OF GASEOUS DISKS IN GALAXIES In summary, gravitational instability is the essential factor of promoting SF in spiral galaxies. ... Becoming overstable, gas layer slows down its SFE, especially for the regions where the volume gas density is low, however the formation of stars still continues at the rate which is much lower now than in the past. ...

... Planets . ... Stars . Exoplanets . ... Most exoplanets so far discovered fall into the category of тАШhot JupitersтАЩ, these are giant planets orbiting very close to their parent star. ... Note that we have discovered so many hot Jupiters because they are the easiest type of planet to find, they are not necessarily particularly common in the galaxy. ... Subsequently several similar hot and€а fuzzy worlds have been discovered the same way, proving this that this planet is not a one-off oddball. ...
