AKARI's infrared view on nearby stars : Using AKARI Infrared Camera All-Sky Survey, 2MASS, and Hipparcos catalog
Y. Ita, M. Matsuura, D. Ishihara +11
Results: We found that the (B-V) v.s. (V-S9W) color-color diagram is useful to identify the stars with infrared excess emerged from circumstellar envelopes/disks. Be stars with inf…

--Results-- We found that the (B-V) v.s. (V-S9W) color-color diagram is useful to identify the stars with infrared excess emerged from circumstellar envelopes/disks. Be stars with…
AKARI Near- to Mid-Infrared Imaging and Spectroscopic Observations of the Small Magellanic Cloud. I. Bright Point Source List
Y. Ita, T. Onaka, T. Tanabe +9
We carried out a near- to mid-infrared imaging and spectroscopic observations of the patchy areas in the Small Magellanic Cloud using the Infrared Camera on board AKARI. Two 100 ar…
An AKARI Search for Intracluster Dust of Globular Clusters
N. Matsunaga, H. Mito, Y. Nakada +7
We report the observations of 12 globular clusters with the AKARI/FIS. Our goal is to search for emission from the cold dust within clusters. We detect diffuse emissions toward NGC…
Very early multi-color observations of the plateau phase of GRB 041006 afterglow
Y. Urata, K. Y. Huang, Y. L. Qiu +17
Observations of the optical afterglow of GRB 041006 with the Kiso Observatory 1.05 m Schmidt telescope, the Lulin Observatory 1.0 m telescope and the Xinglong Observatory 0.6 m tel…
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…
Kiso observations for 20 GRBs in HETE-2 era
Y. Urata, Y. Nakada, T. Miyata +7
We have established a GRB follow-up observation system at Kiso observatory (Japan) in 2001. Since the east Asian area had been blank for the GRB follow-up observational network, th…
SiO Maser Survey of the Large-Amplitude Variables in the Galactic Center
S. Deguchi, H. Imai, T. Fujii +7
We have surveyed ~400 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 179 detections. SiO lines we…
Interstellar extinction in the open clusters towards galactic longitude around 130 degrees
A K Pandey, K Upadhyay, Y Nakada +1
In this paper we present a detailed study of the intra-cluster reddening material in the young open clusters located around using colour-excess diagrams and two-colo…
Pulsation at the tip of the first giant branch?
Yoshifusa Ita, Toshihiko Tanabé, Noriyuki Matsunaga +10
The first results of our ongoing near-infrared (NIR) survey of the variable red giants in the Large Magellanic Cloud, using the Infrared Survey Facility (IRSF) and the SIRIUS infra…
