We present an analysis of high resolution Chandra spectra of late-type stars. Our sample includes giant stars from the Hetzsprung gap to the ''clump'' phase...

The First Billion Years is one of the largest and most comprehensive cosmological, hydrodynamical simulation of the early Universe to date. It studies the...

There are two main types of photoionized gaseous nebulae that exist in the universe: H II regions and Planetary Nebulae (PNe). They mark the endpoints of...

We report the first extrasolar planet, ET1, detected with a new generation Doppler instrument, called Exoplanet Tracker. This planet has a minimum mass of 0.41...

The empirical study of confirmed brown dwarfs began in 1995. Until this year, however, no ironclad examples of free-floating field brown dwarfs have been...

Polarized emission from aligned interstellar dust is both a crucial tool for studies of magnetism in the interstellar medium and a troublesome contaminant in...
