How to tell that a young stellar object is really young

Many aspects of the star forming process, especially the process to form massive stars (greater than 8 solar masses), remain unknown. This paper distinguishes between two stages of star formation by fitting models to observations of several young stellar objects in the giant molecular cloud G333. Continue reading


The Optimum Way to Board a Plane

In fact, at yesterday’s morning coffee discussion here at UCSC, there was a bit of surprise that this particular paper was cross-listed … Continue reading

Observing the “supernova of the generation” with Keck

Last night, I was in the Berkeley-based remote control room of the Keck telescope watching Professor Josh Bloom and his team follow up what Bloom claims to be the “supernova of the generation.”  PTF11kly, a type Ia supernova discovered by the Palomar Transient Factory in California, is one of the earliest and closest type Ia supernovae … Continue reading

Buoyancy in Action

Ever wonder how sunspots are formed? This paper takes a close look at how the magnetic structures that give rise to sunspots make it all the way from the deep solar interior to its surface. Continue reading
