Don't believe the hype(r): The Yellow Supergiants of Westerlund 1

Emma R. Beasor, Nathan Smith, Jennifer E. Andrews

Yellow hypergiants (YHGs) are often presumed to represent a transitional post-red supergiant (RSG) phase for stars 30-40 \msun. Here we present visual-wavelength echelle spec…

The detailed chemical abundance patterns of accreted halo stars from the optical to infrared

Andreia Carrillo, Keith Hawkins, Paula Jofré +3

Understanding the assembly of our Galaxy requires us to also characterize the systems that helped build it. In this work, we accomplish this by exploring the chemistry of accreted…

Radio Spectral Index Analysis of Southern Hemisphere Symbiotic Stars

John M. Dickey, J. H. S. Weston, J. L. Sokoloski +2

Symbiotic stars show emission across the electromagnetic spectrum from a wide array of physical processes. At cm-waves both synchrotron and thermal emission is seen, often highly v…

Searching for active low-mass stars in CMa star-forming region: multi-band photometry with T80S

J. Gregorio-Hetem, F. Navarete, A. Hetem +10

An exotic environment surrounds the young stellar groups associated with the Canis Major (CMa) OB1/R1 region, which probably was formed under feedback from at least three supernova…

Very Long Baseline Interferometry imaging of the advancing ejecta in the first gamma-ray nova V407 Cyg

M. Giroletti, U. Munari, E. Körding +7

In 2010/3, the Large Area Telescope on board Fermi revealed a transient gamma-ray source, positionally coincident with the optical nova in the symbiotic binary, V407Cyg. This event…

The Gemini Planet Imager view of the HD 32297 debris disk

Gaspard Duchene, Malena Rice, Justin Hom +60

We present new -band scattered light images of the HD 32297 edge-on debris disk obtained with the Gemini Planet Imager (GPI). The disk is detected in total and polarized intensi…
