A search was made for GHz line emission from water vapor in the direction of twelve Mira and two semiregular variables. Upper limits to the emission are in the range of to Jy. It is estimated that thermal emission from the inner regions of late type stellar envelopes will be on the order of ten Jy. Maser emission, according to one model, would be an order of magnitude by: 2. Get this from a library! A Search for GHz emission from water in late-type stars. [T B H Kuiper; Ames Research Center.;]. A search was made for GHz line emission from water vapor in the direction of twelve Mira and two semiregular variables. Upper limits to the emission are in the range of to Jy. It is estimated that thermal emission from the inner regions of late type stellar envelopes will be on the order of ten Jy. We have searched for water vapor emission at GHz, redshifted at GHz and GHz, in the two ultraluminous starburst galaxies Mrk and VIIZw

SAO/NASA Astrophysics Data System (ADS) Title: A search for GHz emission from water in late-type stars Authors: Kuiper, T. B. H., Swanson, P. N., Dickinson, D. F. The Astrophysics of Emission Line Stars offers general information on emission line stars, starting from a brief introduction to stellar astrophysics, and then moving toward a broad overview of emission line stars including early and late type stars as well as pre-main sequence stars. Detailed references have been prepared along with an index. Cool Stars, Stellar Systems, and the Sun Broadband linear polarization and chromospheric CA II H and K emission in late-type main sequence stars. Pages Cool Stars, Stellar Systems, and the Sun Book Subtitle Proceedings of the Fifth Cambridge Workshop on Cool Stars, Stellar Systems, and the Sun Held in Boulder, Colorado, July 7. Water molecules are also present in interstellar space where they can be formed e.g. in the protection of dust particles (protection against short wavelength radiation). Even in sunspots water molecules have been detected. Water Masers which are extremely strong sources of water line emission Author: Arnold Hanslmeier.

  A search for X-Ray luminous late type stars in NIPSS data.- The Wilson-Bappu relationship - a barometric effect.- Sensitivity of the H? line to expansion, geometrical extent and temperature gradient in the G and K supergiant chromospheres.- Radio continuum emission from the ionized stellar winds of the cool supergiants in zeta aurigae-like. The contributions in this volume discuss the magnetic structures in the outer atmospheres of active late-type stars, and in particular the various methods available for imaging surface features on these objects. Emphasis has been laid upon multiwavelength studies of the phenomena and the application of solar astrophysics to stellar objects. The book is recommended to research workers or. In February, brief observations at GHz were made of Ori MCI as an instrumental check while conducting a se,arch for Gllz emission from late type stars (Kuiper ~ al. ). Relative to the previous observations of and , the peak antenna temperature was nearly twice as strong.   Emission line stars are attractive to many people because of their spectacular phenomena and their amazing varieties and variability. This book offers general information on emission line stars, starting from a brief introduction to stellar astrophysics and then moving to a broad overview of emission line stars including early and late type stars as well as pre-main sequence Edition: Ed.
