Further Detections of Oh Masers in Carbon Stars with Silicate Features
نویسنده
چکیده
A sample of J–type carbon stars was searched for OH maser emission. The new detection of three OH lines towards two silicate carbon stars is reported. In V778Cyg, previously known as the main–lines (1665 and 1667MHz) maser source, the satellite 1612MHz emission was discovered while in NSV2814 the main OH lines were detected. The presence of OH maser lines confirms the former suggestion that oxygen–rich material is located in the vicinity (≈ 10 cm) of silicate carbon stars.

Circular Polarization of Water Masers in the Circumstellar Envelopes of Late Type Stars
We present circular polarization measurements of circumstellar H2O masers. The magnetic fields in circumstellar envelopes are generally examined by polarization observations of SiO and OH masers. SiO masers probe the high temperature and density regime close to the central star. OH masers are found at much lower densities and temperatures, generally much further out in the circumstellar envelop...
متن کاملObservations of Stellar Maser Sources with no IRAS Counterpart
We investigated stellar maser sources with no IRAS counterpart at the radio, middle-infrared, and nearinfrared wavelengths. A 43 GHz SiO maser search for 120 2MASS/MSX objects, and 10 OH 1612 MHz sources with no or a very faint MSX counterpart, resulted in 43 SiO detections: one OH 1612 MHz source, 2 near-infrared stars, and 40 MSX sources. Additional near-infrared J-, H-, and K-band observatio...
متن کاملDetections of SiO Masers from the Large-Amplitude Variables in the Galactic Nuclear Disk
We have surveyed known large-amplitude variables within 15 of the Galactic center in the SiO J =1–0 v = 1 and 2 maser lines at 43 GHz, resulting in 79 detections and 58 non-detections. The detection rate of 58 percent is comparable to that obtained in Bulge IRAS source surveys. SiO lines were also detected from four other sources near the program objects. The SiO detection rate increases steepl...
متن کاملA self-consistent model of a 22 GHz water maser in a dusty environment near late-type stars
We study the conditions for operation of the 22 GHz ortho-water maser in a dusty medium near late-type stars. The main physical processes, such as exchange of energy between dust and gas in the radiation field of a star, radiative cooling by water molecules and pumping of water masers are described self-consistently. We show that the presence of dust grains of various types (or of one type with...
متن کاملThe ISO-SWS spectrum of NML Cyg
The high resolution spectrum of NML Cyg observed with the ISO-SWS in its slow-speed grating mode (2.4-45 m) shows a wealth of features never seen before in previous observations. These include ro-vibrational lines of H2O at 2.7 and 6.2 m, of OH between 3 and 3.5 m and a deep absorption band of CO2 at 4.26 m. We also report on the detection of pure rotational emission lines of H2O between 35 and...
