3-D Dynamics of Interactions between Stellar Winds and the Interstellar Medium as Seen by AKARI and Spitzer
Toshiya Ueta, Hideyuki Izumiura, Issei Yamamura +9
Recent far-infrared mapping of mass-losing stars by the AKARI Infrared Astronomy Satellite and Spitzer Space Telescope have suggested that far-infrared bow shock structures are pro…
Mass Loss History of the AGB star, R Cas
Toshiya Ueta, Robert E. Stencel, Issei Yamamura +9
We report here on the discovery of an extended far-infrared shell around the AGB star, R Cassiopeia, made by AKARI and Spitzer. The extended, cold circumstellar shell of R Cas span…
A multi-site campaign to measure solar-like oscillations in Procyon. I. Observations, Data Reduction and Slow Variations
Torben Arentoft, Hans Kjeldsen, Timothy R. Bedding +45
We have carried out a multi-site campaign to measure oscillations in the F5 star Procyon A. We obtained high-precision velocity observations over more than three weeks with eleven…
Asymmetric silicate dust distribution toward the silicate carbon star BM Gem
Keiichi Ohnaka, Hideyuki Izumiura, Christoph Leinert +3
Silicate carbon stars show the 10 micron silicate emission, despite their carbon-rich photospheres. They are considered to have circumbinary or circum-companion disks, which serve…
Detection of Fluorine in the Halo Planetary Nebula BoBn 1: Evidence For a Binary Progenitor Star
Masaaki Otsuka, Hideyuki Izumiura, Akito Tajitsu +1
We have found the fluorine lines [F IV] 3996.92A,4059.90A in the extremely metal-poor ([Ar/H] = -2.10+/-0.21) halo planetary nebula (PN) BoBn 1 in high-dispersion spectra from the…
Evidence for a companion to BM Gem, a silicate carbon star
Hideyuki Izumiura, Kunio Noguchi, Wako Aoki +12
Balmer and Paschen continuum emission as well as Balmer series lines of P Cygni-type profile from H_gamma through H_23 are revealed in the violet spectra of BM Gem, a carbon star a…
