Cool Star Lab Presents at Cool Stars Conference


Adam Burgasser and Daniella Bardalez Gagliuffi were among hundreds of attendees at the 18th Cambridge Workshop on Cool Stars, Stellar Systems and the Sun, held in Flagstaff, AZ, June 8-13.  This biennial conference highlights the latest research in low-temperature, low-mass stars and brown dwarfs, and this year had its fair share of exciting results in both observation and theory.

Cool Star Undergrads Present Work at UCSD Research Conference

14003454126_1eac67154c_mAishwarya Iyer and Melisa Tallis both presented 15 minute talks on their research work today at the 27th Annual UCSD Undergraduate Research Conference.  The conference recognizes outstanding scholarly work produced by UC San Diego undergraduates, and all participating students are nominated by faculty who have judged their work to be outstanding. Aisha presented her work on Spitzer monitoring of the TWA 30AB system (“Mid-infrared Variability of the Low Mass Stellar Binary TWA 30 A and B”); Melisa presented her work searching for young brown dwarfs in the SpeX Prism Spectral Library (“Identifying Young Brown Dwarfs Near the Sun”).

Aisha Iyer Presents Research on TWA 30AB at American Physical Society Meeting

IMG_0256Aisha Iyer, an undergraduate researcher in the Cool Star Lab, attended the April 2014 American Physics Society Meeting in Savannah, GA, to present a poster on her research: Spitzer monitoring observations of TWA 30AB.  She was the recipient of an APS FPD Scholar Travel Award and supported by the UCSD Physics Department for her trip. Here’s what Aisha had to say about the experience:

Cloud properties of Nearest Brown Dwarfs Revealed through Spectral Monitoring Study

starweatherWe’ve just reported the first results from our April 2013  campaign to monitor the nearby brown dwarf binary Luhman 16AB, in a paper published in the Astrophysical Journal.  Our results confirm the earlier “flux reversal” seen in FIRE spectroscopy, and allow us to make the first constraints on the cloud coverage fraction and the temperatures of the “clouds” and “holes” in the atmosphere of Luhman 16B.  We also confirm an apparent correlation between rotation period and variability amplitude, which may emerge if cloud features are related to the Rhine’s scale of brown dwarf atmospheres.
