A nearby young M dwarf with a wide, possibly planetary-mass companion
(2016-04-11)
We present the identification of two previously known young objects in the solar neighbourhood as a likely very wide binary. TYC 9486-927-1, an active, rapidly rotating early-M dwarf, and 2MASS J21265040-8140293, a low-gravity ...
A search for white dwarfs in the Galactic plane: : the field and the open cluster population
(2016-04-01)
We investigated the prospects for systematic searches of white dwarfs at low Galactic latitudes, using the VLT Survey Telescope (VST) H$\alpha$ Photometric Survey of the Galactic plane and Bulge (VPHAS+). We targeted 17 ...
Calibrated and completeness-corrected optical stellar density maps of the Northern Galactic Plane
(2016-03-21)
Following on from the second release of calibrated photometry from IPHAS, the INT/WFC Photometric Hα Survey of the Northern Galactic Plane, we present incompleteness-corrected stellar density maps in the r and i photometric ...
VISION - Vienna survey in Orion I. VISTA Orion A Survey
(2016-03-07)
Orion A hosts the nearest massive star factory, thus offering a unique opportunity to resolve the processes connected with the formation of both low- and high-mass stars. Here we present the most detailed and sensitive ...
Iron-Group Abundances in the Metal-Poor Main Sequence Turnoff Star HD~84937
(2016-01-20)
We have derived new very accurate abundances of the Fe-group elements Sc through Zn (Z = 21-30) in the bright main-sequence turnoff star HD 84937, based on high-resolution spectra covering the visible and ultraviolet ...
