Astrochemistry: April 2013

A research team with Jungmi Kwon (GUAS/NAOJ) has performed deep imaging linear and circular polarimetry (Note 1) of the 'Cat's Paw Nebula' (NGC 6334) (Note 2) located in the constellation Scorpius, successfully detecting high degrees of circular polarization (CP) of as much as 22% in NGC 6334. The detected CP degree is the highest ever observed.

One postdoctoral position in experimental physical chemistry and chemical physics (reaction dynamics, astrobiology, astrochemistry) is open at the Department of Chemistry, University of Hawai'i at Manoa, for the period of one year, initially, to investigate the formation of dipeptides in astrophysically relevant ices by ionizing radiation.

The Astrobiology group at Arizona State University is proud to sponsor Stellar Stoichiometry, April 11-12, 2013. This workshop will examine the growing evidence that elemental abundance ratios of stars vary considerably from solar, and discuss the consequences of elemental variability on the existence and habitability of planets. To this end we are bringing together many of the world's leading stellar spectroscopists to figure out why abundance ratios derived by different groups vary significantly, and to figure out what are the true intrinsic variations. The workshop can be attended in person at ASU or virtually, anywhere in the world.
