The Chemical Enrichment History of the Small Magellanic Cloud and Its Gradients
Ricardo Carrera, Carme Gallart, Antonio Aparicio +3
We present stellar metallicities derived from Ca II triplet spectroscopy in over 350 red giant branch stars in 13 fields distributed in different positions in the SMC, ranging from…
Three active M dwarfs within 8 pc: L 449-1, L 43-72, & LP 949-15
R. -D. Scholz, G. Lo Curto, R. A. Méndez +4
Three nearby star candidates were selected as bright 2MASS point sources without associated optical sources, i.e. with potentially large proper motions, subsequently confirmed by m…
Searching for White and Brown Dwarfs in the frame of the MUSYC/CYDER survey
M. Altmann, R. A. M'endez, M. -T. Ruiz +4
MUSYC (MUltiwavelength Survey by Yale and Chile), and its predecessor, the CYDER (Cal'an Yale Deep Extragalactic Research) survey are both deep multiwavelength surveys mainly aimin…
Faint blue objects on the Hubble Deep Field North & South as possible nearby old halo white dwarfs
R. A. Méndez, D. Minniti
Using data derived from the deepest and finest angular resolution images of the universe yet acquired by astronomers at optical wavelengths using the Hubble Space Telescope (HST) i…
A large local rotational speed for the Galaxy found from proper-motions: Implications for the mass of the Milky-Way
René A. Méndez, Imants Platais, Terrence M. Girard +2
Predictions from a Galactic Structure and Kinematic model are compared to the absolute proper-motions of about 30,000 randomly selected stars with derived fr…
A new optical reddening model for the Solar neighborhood: Galactic Structure through low-latitude starcounts from the Guide Star Catalogue
R. A. Mendez, W. F. van Altena
A new optical reddening model for the Solar neighborhood is presented. The model makes use of the large-scale properties of the dust layer in the Galaxy, and of the observed clumpi…
