Search for SiO masers in nearby Miras pulsating in the first overtone mode
Yoshifusa Ita, Shuji Deguchi, Noriyuki Matsunaga +1
We studied the period-K magnitude (P-K) relations of nearby Mira and Mira-like variables with relatively good Hipparcos parallaxes. They form at least two prominent sequences on th…
Mira variables in the Galactic bulge with OGLE-II data
N. Matsunaga, H. Fukushi, Y. Nakada
We have extracted a total of 1968 Mira variables from the OGLE-II data base in the Galactic bulge region. Among them, 1960 are associated with 2MASS sources, and 1541 are further i…
Red Variables in Globular Clusters: Comparison with the Bulge and the LMC
N. Matsunaga, Y. Nakada, T. Tanabe +2
We are conducting a project aimed at surveys and repeated observations of red variables (or long-period variables) in globular clusters. Using the IRSF/SIRIUS near-infrared facilit…
Detection of SiO Maser Emission in V838 Mon
Shuji Deguchi, Noriyuki Matsunaga, Hinako Fukushi
We report on the detection of 43 GHz SiO maser emission in V838 Mon, a prototype of a new class of eruptive variables, in which a red supergiant was formed after the nova-like erup…
