Carbon stars in the IRTS survey
T. Le Bertre, M. Tanaka, I. Yamamura +2
We have identified 139 cool carbon stars in the near-infrared spectro-photometric survey of the InfraRed Telescope in Space (IRTS) from the conspicuous presence of molecular absorp…
Diffuse X-rays in the Galactic center region -- The zoo of iron line clumps, non-thermal filaments and hot plasmas --
Aya Bamba, Hiroshi Murakami, Atsushi Senda +3
This paper reports the diffuse X-ray features around the Galactic center observed with Chandra. We confirm the ASCA and Ginga discoveries of the large-scale thin-thermal plasma wit…
X-ray source population of the Galactic center region obtained with ASCA
Masaaki Sakano, Katsuji Koyama, Hiroshi Murakami +3
From the ASCA X-ray point-source list in the Galactic center 5x5 degree^2 region, we found the clear correlation between the position of the sources and the absorption. This fact i…
Water Vapor Absorption in Early M-type Stars
M. Matsuura, I. Yamamura, H. Murakami +2
The spectrometers onboard the Infrared Telescope in Space (IRTS) reveal water vapor absorption in early M-type stars, as early as M2. Previous observations detected H_2O vapor abso…
SNRs in the Galactic Center region observed with ASCA
M. Sakano, J. Yokogawa, H. Murakami +3
We report the ASCA results of the supernova remnants (SNRs) and their candidates in the Galactic Center region. We found apparent X-ray emission from G359.1-0.5 and G0.9+0.1, and m…
