"Dwarf galaxies are typically very faint, and are therefore hard to find. Given that, what are our chances of finding their distant ancestors, located billions of light-years away? A recent study aims to find out."
The AAS awards Dr. Karin I. Öberg the Pierce Prize for her research on the astrochemistry and astrophysics of ices and molecules in star-forming regions and proto-planetary disks. The panel recognizes Dr. Öberg’s scientific leadership in her ability to identify important, well-defined, and tractable problems, yielding fundamental advances in the field of star and planet formation.

Graduate student Catherine Zucker’s research was featured on the American Astronomical Society’s “Nova” (News) site! Cara Battersby, SMA postdoc collaborator & Catherine’s REU mentor is the other co-author.
Stars are assembled in molecular clouds when matters condense and collapse under the gravitational pull. Massive stars (M > 8 Msun) are found mostly in clusters together with lower mass stellar objects (Lada & Lada 2003). How parsec-scale, massive molecular clumps collapse and fragment to give rise to a cluster of stars has been one of the central questions in star formation in the past decade. Jeans mass, the characteristic mass of fragments, is 1Msun for typical physical conditions in (pre) cluster forming clumps (Zhang et al. 2009, 2015).

"Archaeologists and astronomers don’t seem to have much in common. One digs into the earth while the other looks at the sky, and a stone tool once wielded by Homo erectus couldn’t be more different from an exploding star at the edge of the visible universe...
"Our Sun is a relatively quiet star that only occasionally releases solar flares or blasts of energetic particles that threaten satellites and power grids. You might think that smaller, cooler stars would be even more sedate. However, astronomers have now identified a tiny star with a monstrous temper. It shows evidence of much stronger flares than anything our Sun produces. If similar stars prove to be just as stormy, then potentially habitable planets orbiting them are likely to be much less hospitable than previously thought" Read more about Tiny, Ultracool Star is Super Stormy
