A Census of Thermally-Pulsing AGB stars in the Andromeda Galaxy and a First Estimate of their Contribution to the Global Dust Budget
Steven R. Goldman, Martha L. Boyer, Julianne Dalcanton +5
We present a near-complete catalog of the metal-rich population of Thermally-Pulsing Asymptotic Giant Branch stars in the northwest quadrant of M31. This metal-rich sample compleme…
Galaxy populations in the Hydra I cluster from the VEGAS survey I. Optical properties of a large sample of dwarf galaxies
Antonio La Marca, Reynier Peletier, Enrichetta Iodice +17
At ~50 Mpc, the Hydra I cluster of galaxies is among the closest cluster in the z=0 Universe, and an ideal environment to study dwarf galaxy properties in a cluster environment. We…
Optical and near-infrared spectroscopy of Nova V2891 Cygni: evidence for shock-induced dust formation
Vipin Kumar, Mudit K. Srivastava, Dipankar P. K. Banerjee +6
We present multi-epoch optical and near-infrared observations of the highly reddened, \pion{Fe}{ii} class slow nova V2891 Cygni. The observations span 15 months since its discovery…
A Linear Relation Between the Color Stretch and the Rising Color Slope of Type Ia Supernovae
Ping Chen, Subo Dong, Chris Ashall +34
Using data from the Complete Nearby () sample of Type Ia Supernovae (CNIa0.02), we discover a linear relation between two parameters derived from the color cur…
Dynamics of irregularly-shaped cometary particles subjected to outflowing gas and solar radiative forces and torques
Fernando Moreno, Daniel Guirado, Olga Muñoz +6
The dynamics of irregularly-shaped particles subjected to the combined effect of gas drag and radiative forces and torques in a cometary environment is investigated. The equations…
The Gaia-ESO Survey: Target selection of open cluster stars
A. Bragaglia, E. Alfaro, E. Flaccomio +36
The Gaia-ESO Survey (GES) is a public, high-resolution spectroscopic survey with FLAMES@VLT. GES targeted in particular a large sample of open clusters (OCs) of all ages. The diffe…
