Results 41 to 50 of about 121 (110)
We present the results from long-term simultaneous monitoring observations of SiO and H _2 O masers toward the Mira variable star WX Serpentis. This study has been conducted with 21 m single-dish radio telescopes of the Korean VLBI Network from 2009 June

SiO v = 1 J = 5 → 4 Maser Emission from the Root of the “Water Fountain” Source W 43A
We report here the first mapping of SiO v = 1 J = 5 → 4 maser emission toward the “water fountain” source W 43A in order to explore the central stellar system driving the collimated, bipolar, fast jet.

Asymptotic giant branch stars in the GLIMPSE database
Aims. The GLIMPSE database contains over one hundred million point sources between longitudes of −60° and +60° and most of these are asymptotic giant branch (AGB) stars within 16 kpc from the Sun.

Imaging the Jet of MWC 349A with Resolved Radio Recombination Line Emission from ALMA
Jets and disk winds arise from materials with excess angular momentum ejected from the accretion disks in forming stars. How these structures are launched and how they impact the gas within the innermost regions of these objects remains poorly understood.

A 6 cm Formaldehyde Line Survey toward WISE Point Sources
We conducted a 6 cm formaldehyde (H _2 CO) line survey across the northern sky, targeting 3149 high-mass star-forming region candidates selected from the all-sky Wide-field Infrared Survey Explorer (WISE) point-source catalog using the Shanghai TianMa 65

Studies of variability of circumstellar H2O masers [PDF]
From March 1980 to December 1983, the author took part in regular observations of variability of maser radio emission in the H2O line at 22 GHz. The observations were carried out at the 22-meter radio telescope of the P. Lebedev Physical Institute (USSR Academy of Sciences) in Pushchino (Moscow Region).

Variability of masers in circumstellar shells on timescales of decades
AbstractBased on a 15–20 year long monitoring program of H2O masers and new observations of OH masers discovered 35 years ago, we studied the variability of maser emission in AGB stars over timescales of decades. The H2O maser features in the semi-regular variable stars RX Boo and SV Peg, and of the Mira stars U Her and R Cas, showed strong ...
