Large proper motions in the jet of the high-mass YSO cepheus a HW2
(2006-02-20)
Using high angular resolution ( 0B25–0B05) Very Large Array (VLA) observations made at 3.6 cm, 1.3 cm, and
7 mm during the period 1991–2004, we report the detection of large proper motions in the components of the ...
The circumstellar structure and excitation effects around the massive protostar Cepheus A HW 2
(2007)
We report SMA 335 GHz continuum observations with angular resolution of similar to 0.3'', together with VLA ammonia observations with similar to 1'' resolution toward Cep A HW 2. We find that the flattened disk structure ...
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, ...
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 ...
Description of the female and larva of Phyllogomphoides joaquini Rodrigues Capitulo, 1992 (Anisoptera: Gomphidae)
(Societas Internationalis Odonatologica, 2006)
The 9 and last larval instar are described and illustrated based on specimens from Argentina (Buenos Aires province). The 9 is unique in the possession of a subapical tooth on each lobe of the vulvar scale, and it can be ...
Water Maser Microstructures in Cepheus AIn Galactic Star Formation Across the Stellar Mass Spectrum
(De Buizer, J, Van der Bliek, N.PASP/USA, 2020)
The distribution of the warm and dense molecular gas around Cepheus A HW 2
(1999)
We present VLA observations of the J; K 1; 1 , (2, 2), (3, 3) and (4, 4) inversion
transitions of NH3 toward the HW 2 object in Cepheus A, with 1-arcsec angular resolution.
Emission is detected in the main hyperfine ...
1.3 mm Polarized emission in the circumstellar disk of a massive protostar
(IOP Publishing, 2016-12)
We present the first resolved observations of the 1.3 mm polarized emission from the disk-like structure surrounding the high-mass protostar Cepheus A HW2. These CARMA data partially resolve the dust polarization, suggesting ...
