Spectroscopic Determination of Stellar Atmospheric Parameters: Application to Mid-F through Early-K Dwarfs and Subgiants
Sato, Bun'ei; Kambe, Eiji; Takeda, Yoichi +2 more
Takeda et al.'s (2002, PASJ, 54, 451) method for the spectroscopic determination of stellar atmospheric parameters (Teff, logg, vt, and [Fe/H]) from the equivalent widths of Fe I and Fe II lines was applied to 32 dwarfs/subgiants of mid-F through early-K types based on high-quality echelle spectra obtained at Okayama Astrophy…
A New Empirical Method for Estimating the Far-Infrared Flux of Galaxies
Onaka, Takashi; Takeuchi, Tsutomu T.; Shibai, Hiroshi +1 more
We propose a new empirical method to estimate the total far-infrared flux of galaxies from the spectral energy distribution (SED) at wavelengths of λ <= 100 µm. It is difficult to derive the total far-infrared luminosity from only the IRAS data, though it is one of the most important properties of galaxies. Observations by Infrared Telesc…
A Multi-Band Photometric Study of Tidal Debris in a Compact Group of Galaxies: Seyfert's Sextet
Nagao, Tohru; Taniguchi, Yoshiaki; Sanders, David B. +4 more
In order to investigate the properties of the prominent tidal debris feature extending to the northeast of a compact group of galaxies, Seyfert's Sextet, we analyzed multi-band (U, B, V, VR, R, I, J, H, and K') photometric imaging data and obtained the following results: 1) The radial surface brightness distribution of this tidal debris in Seyfert…
