Ultra-Deep Hubble Space Telescope Imaging of the Small Magellanic Cloud: The Initial Mass Function of Stars with M <~ 1 Msun
Jason S. Kalirai, Jay Anderson, Aaron Dotter +7
We present a new measurement of the stellar initial mass function (IMF) based on ultra-deep, high-resolution photometry of >5,000 stars in the outskirts of the Small Magellanic Clo…
The LF of TP-AGB stars in the LMC and SMC
Gustavo Bruzual, Stephane Charlot, Rosa Gonzalez Lopezlira +3
We show that Montecarlo simulations of the TP-AGB stellar population in the LMC and SMC galaxies using the CB* models produce LF and color distributions that are in closer agreemen…
The UV Luminosity Function of star-forming galaxies via dropout selection at redshifts z ~ 7 and 8 from the 2012 Ultra Deep Field campaign
Matthew A. Schenker, Brant E. Robertson, Richard S. Ellis +13
We present a catalog of high redshift star-forming galaxies selected to lie within the redshift range z ~ 7-8 using the Ultra Deep Field 2012 (UDF12), the deepest near-infrared (ne…
The First Reported Infrared Emission from the SN 1006 Remnant
P. Frank Winkler, Brian J. Williams, William P. Blair +5
We report results of infrared imaging and spectroscopic observations of the SN 1006 remnant, carried out with the Spitzer Space Telescope. The 24 micron image from MIPS clearly sho…
The rotation rates of massive stars: the role of binary interaction through tides, mass transfer and mergers
S. E. de Mink, N. Langer, R. G. Izzard +2
Rotation is thought to be a major factor in the evolution of massive stars, especially at low metallicity, with consequences for their chemical yields, ionizing flux and final fate…
Magnetic Activity Cycles in the Exoplanet Host Star epsilon Eridani
T. S. Metcalfe, A. P. Buccino, B. P. Brown +7
The active K2 dwarf epsilon Eri has been extensively characterized, both as a young solar analog and more recently as an exoplanet host star. As one of the nearest and brightest st…
