... October 2, 1999 . Phi Persei: Double Star . ... Based on recent results , this artist's vision of the double star Phi Persei , 720 light years away, shows a bright, rapidly rotating massive star surrounded by a disk of gas. A small companion star orbits 100 million miles away. ... Ten million years ago the small companion was actually the most massive star in the system and because of its greater mass evolved into a giant star more quickly. ... About APOD > . ...

The H II complex N 44 in the Large Magellanic Cloud (LMC) provides an excellent site to perform a detailed study of star formation in a mild starburst, as it hosts three regions of star formation at different evolutionary stages, and it is not as complicated and confusing as the 30 Doradus giant H II region. We have obtained Spitzer Space Telescope observations and complementary ground-based 4 m uBVIJK observations of N 44 to identify candidate massive young stellar objects (YSOs). ...

The complex interplay between regions of massive star formation and their surroundings is a determining component of galaxy evolution. Winds of massive stars and the resulting supernova explosions inject mechanical energy into the interstellar medium, redistributing gas within a galaxy. ... Return to list of thesis topics . ...

... Stars . ... Cepheid variable stars have been known since the 18th century. ... Regularly brightening to a peak over days, weeks or months before fading these variable stars were remarkable curiosities to astronomers in past centuries.€а The term Cepheid is taken from the star Delta Cephei in the constellation of Cepheus, which was identified as variable€а in 1784 by the teenaged prodigy John Goodricke (1764-96). ...

Pulsars can be used to study the strong nuclear force. The density of matter at the center of neutron stars is one or two orders of magnitude larger than the density of atomic nuclei. ... Very "soft" EOSs predict lower pressures for a given density, i.e., highly compressible matter. ... If more precise measurements can confirm this high value, then many model EOSs for dense matter can be ruled out. ... Another way of studying the behavior of super-dense matter is to find fast pulsars. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
