Near-infrared photometry and spectroscopy of the low Galactic latitude globular cluster 2MASS-GC03
(2016-10-11)
We present deep near-infrared photometry and spectroscopy of the globular cluster 2MASS-GC03 projected in the Galactic disk using MMIRS on the Clay telescope (Las Campanas Observatory) and VISTA Variables in the Via Lactea ...
Discovery of a Long-Lived, High Amplitude Dusty Infrared Transient
(2016-08-11)
We report the detection of an infrared selected transient which has lasted at least 5 years, first identified by a large mid-infrared and optical outburst from a faint X-ray source detected with the Chandra X-ray Observatory. ...
Physical parameters of IPHAS-selected classical Be stars. (I. Determination procedure and evaluation of the results.)
(2016-07-01)
We present a semi-automatic procedure to obtain fundamental physical parameters and distances of classical Be (CBe) stars, based on the Barbier-Chalonge-Divan (BCD) spectrophotometric system. Our aim is to apply this ...
The Population of Compact Radio Sources in the Orion Nebula Cluster
(2016-05-10)
We present a deep centimeter-wavelength catalog of the Orion Nebula Cluster (ONC), based on a 30h single-pointing observation with the Karl G. Jansky Very Large Array in its high-resolution A-configuration using two 1 GHz ...
Probing the Dragonfish star-forming complex: : the ionizing population of the young massive cluster Mercer 30
(2016-05-01)
The Dragonfish Nebula has been recently claimed to be powered by a superluminous but elusive OB association. Instead, systematic searches in near-infrared photometric surveys have found many other cluster candidates on ...
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 ...
