In the proposed project, a summer student can use this image database to study the environments of a sample of high-mass proto-stellar objects (HMPOs) which contain massive stars in the earliest stages of their lives. ... A student who will work on this project will learn how to analyze X-ray data using existing and previously tested software (CIAO, Sherpa), and perform comparisons between the X-ray, infrared and optical data. ...

P hobos ("FOH bus") is the larger and innermost of Mars' two moons. Phobos is closer to its primary than any other moon in the solar system, less than 6000 km above the surface of Mars. ... P hobos orbits Mars below the synchronous orbit radius . ... P hobos and Deimos may be composed of carbon-rich rock like C-type asteroids. ... New images from Mars Global Surveyor indicate the Phobos is covered with a layer of fine dust about a meter thick, similar to the regolith on the Earth's Moon. ...

Dust around Herbig Ae/Be Stars: Porous, Cometary-like Grains? ... This brings up the question, which we try to answer here, of how the grain porosity affects the observational manifestations of the dust shells of HAeBe stars: the excess infrared emission, anomalous extinction in the ultraviolet, and the peculiar behaviour of colour indices and linear polarization during deep brightness minima observed for about 25% of HAeBe stars (UX Ori, WW Vul, etc). ...

... 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. ...
