Uncertainties in the production of p nuclei in massive stars obtained from Monte Carlo variations
(2016-12-21)
Nuclear uncertainties in the production of $p$ nuclei in massive stars have been quantified in a Monte Carlo procedure. Bespoke temperature-dependent uncertainties were assigned to different types of reactions involving ...
Highly variable young massive stars in ATLASGAL clumps
(2016-12-05)
High-amplitude variability in Young Stellar Objects (YSOs) is usually associated with episodic accretion events. It has not been observed so far in massive YSOs. Here, the high-amplitude variable star sample of ContrerasPena ...
MagAO Imaging of Long-period Objects (MILO). II. A Puzzling White Dwarf around the Sun-like Star HD 11112
(2016-11-10)
HD 11112 is an old, Sun-like star that has a long-term radial velocity (RV) trend indicative of a massive companion on a wide orbit. Here we present direct images of the source responsible for the trend using the Magellan ...
The Herschel-ATLAS Data Release 1 Paper II : Multi-wavelength counterparts to submillimetre sources
(2016-10-21)
This paper is the second in a pair of articles presenting data release 1 (DR1) of the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS), the largest single open-time key project carried out with the Herschel ...
Variable Stars in the Quintuplet stellar cluster with the VVV Survey
(2016-10-21)
The Quintuplet cluster is one of the most massive star clusters in the Milky Way, situated very close to the Galactic center. We present a new search for variable stars in the vicinity of the cluster, using the five-year ...
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 ...
