Schulz, Norbert S., Allen, Glenn, Bautz, Mark W., Canizares, Claude C., Davis, John, Dewey, Dan, ...
Understanding the origins and distribution of matter in the Universe is one of the most important quests in physics and astronomy. Themes range from astro-particle physics to chemical evolution in...
Structure and Evolution of Pre-Main Sequence Stars (2009)
Schulz, Norbert S., Allen, Glenn, Bautz, Mark W., Canizares, Claude C., Davis, John, Dewey, Dan, ...
Low-mass pre-main sequence (PMS) stars are strong and variable X-ray emitters, as has been well established by EINSTEIN and ROSAT observatories. It was originally believed that this emission was of...
