Detection of a candidate for the exciting source of the expanding water maser bubble in Cepheus A
(2002-06-01)
We report sensitive, high angular resolution VLA 3.6 cm and 7 mm continuum observations toward the starforming
region Cepheus A. Three embedded young stellar objects (YSOs) were found within a projected area of
0 .6#0 ...
Study of the dense molecular gas surrounding the ‘extended green object’ G35.03+0.35
(2012)
We present the results of a new study of the molecular gas associated with the ‘extended
green object’ (EGO) G35.03+0.35. This object, very likely a massive young stellar object, is
embedded in amolecular cloud at the ...
Carbon monoxide in the environs of the star WR16
(EDP Sciences, 2013-03)
Aims. We analyze the carbon monoxide emission around the star WR 16 aiming to study the physical characteristics of the molecular gas linked to the star and to achieve a better understanding of the interaction between ...
Unveiling the birth and evolution of the HII region Sh2-173
(Oxford University Press, 2009-04)
Based on a multiwavelength study, the interstellar medium around the H II region Sh2-173 has been analysed. The ionized region is clearly detected in the optical and the radio continuum images. The analysis of the H I data ...
Molecular gas and star formation towards the IR dust bubble S24 and its environs
(EDP Sciences, 2016-01)
Aims. We present a multiwavelength analysis of the infrared dust bubble S 24 and the extended IR sources G341.220-0.213 and G341.217-0.237 located in its environs. We aim to investigate the characteristics of the molecular ...
Evidence for evolution of the outflow collimation in very young stellar objects
(2003-12-01)
We present Very Long Baseline Array proper-motion measurements of water masers toward two young stellar
objects (YSOs) of the W75 N star-forming region. We find that these two objects are remarkable for having a
similar ...
PHYSICAL CHARACTERISTICS OF G331.5-0.1: THE LUMINOUS CENTRAL REGION OF A GIANT MOLECULAR CLOUD
(The American Astronomical Society, 2013-09-01)
We report molecular line and dust continuum observations toward the high-mass star-forming region G331.5-0.1,
one of the most luminous regions of massive star formation in the Milky Way, located at the tangent region ...
Disk and outflow in Cepheus A-HW2: Interferometric SiO and HCO+ observations
(1999-03-20)
j\3.4 mm toward the Cepheus A East star-forming region. The HCO` line shows emission up to
velocities of D50 km s~1 relative to the ambient cloud velocity. The spatial distribution of the highvelocity
gas is bipolar, ...
Where is OH and does It trace the Dark Molecular Gas (DMG)?
(IOP Publishing Ltd, 2018)
Hydroxyl (OH) is expected to be abundant in diffuse interstellar molecular gas because it forms along with H-2 under similar conditions and forms within a similar extinction range. We have analyzed absorption measurements ...
