870 mu m continuum observations of the bubble-shaped nebula Gum 31
(EDP Sciences, 2015)
Aims. We present here a study of the cold dust in the close environs of the ring nebula Gum 31. We aim at deriving the physical
properties of the molecular gas and dust associated with the nebula, and investigating its ...
A relativistic type Ibc supernova without a detected c-ray burst
(Macmillan, 2010-01-28)
Long duration c-ray bursts (GRBs) mark1 the explosive death of some
massive stars and are a rare sub-class of type Ibc supernovae. They are
distinguished by the production of an energetic and collimated relativistic
outflow ...
A relativistic type Ibc supernova without a detected gamma-ray burst
(2010-01)
Long duration c-ray bursts (GRBs) mark1 the explosive death of some
massive stars and are a rare sub-class of type Ibc supernovae. They are
distinguished by the production of an energetic and collimated relativistic
outflow ...
The southern molecular environment of SNR G18.8+0.3 (Research Note)
(EDP Sciences, 2015)
Aims. In a previous paper we investigated the molecular environment toward the eastern border of the supernova remnant (SNR) G18.8+0.3. Continuing with the study of the surroundings of this SNR, we now focus on its southern ...
Spiral Arms in the Disk of HD 142527 from CO Emission Lines with ALMA
(2014-04-10)
In view of both the size of its gap and the previously reported asymmetries and near-infrared spiral arms, the
transition disk of the Herbig Fe star HD 142527 constitutes a remarkable case study. This paper focuses on ...
Spectral imaging of the Sagittarius B2 region in multiple 7-mm molecular lines
(WILEY-BLACKWELL, 2011-03)
We have undertaken a spectral-line imaging survey of a 6 x 6 arcmin2 area around Sagittarius (Sgr) B2 near the centre of the Galaxy, in the range from 30 to 50 GHz, using the Mopra telescope. The spatial resolution varies ...
Multifrequency VLA observations of radio continuum from IRAS 16293-2422
(1991-04-20)
Using the VLA at 20, 6, 2, and 1.3 cm, we observed the cold infrared source IRAS 16293-2422. Our data allow a determination of the spectral indices of the components A and B. IRAS 16293-2422A, which is known from higher ...
VLBA DETERMINATION OF THE DISTANCE TO NEARBY STAR-FORMING REGIONS. V. DYNAMICAL MASS, DISTANCE, AND RADIO STRUCTURE OF V773 Tau A
(2012-01-01)
We present multi-epoch Very Long Baseline Array (VLBA) observations of V773 Tau A, the 51 day binary
subsystem in the multiple young stellar system V773 Tau. Combined with previous interferometric and radial
velocity ...
Outflow-confined H II regions. I. First signposts of massive star formation
(IOP PUBLISHING, 2016)
We present an evolutionary sequence of models of the photoionized disk-wind outflow around forming massive stars based on the Core Accretion model. The outflow is expected to be the first structure to be ionized by the ...
XMMSL1 J074008.2-853927: A tidal disruption event with thermal and non-thermal components
(EDP Sciences, 2017)
Aims. We study X-ray bright tidal disruption events (TDE), close to the peak of their emission, with the intention of understanding the evolution of their light curves and spectra. Methods. CandidateTDEareidentifiedbysear ...
