The period-luminosity relation for type II Cepheids in globular clusters
Noriyuki Matsunaga, Hinako Fukushi, Yoshikazu Nakada +11
We report the result of our near-infrared observations (JHKs) for type II Cepheids (including possible RV Tau stars) in galactic globular clusters. We detected variations of 46 var…
Fe II Emission in 14 Low-Redshift Quasars: I - Observations
Yumihiko Tsuzuki, Kimiaki Kawara, Yuzuru Yoshii +3
We present the spectra of 14 quasars with a wide coverage of rest wavelengths from 1000 to 7300 A. The redshift ranges from z = 0.061 to 0.555 and the luminosity from M_{B} = -22.6…
Broad-band photometric colors and effective temperature calibrations for late-type giants. II. Z<0.02
A. Kucinskas, P. H. Hauschildt, I. Brott +4
(Abridged) We investigate the effects of metallicity on the broad-band photometric colors of late-type giants, and make a comparison of synthetic colors with observed photometric p…
Interstellar Extinction Law in the J, H, and Ks Bands toward the Galactic Center
Shogo Nishiyama, Tetsuya Nagata, Nobuhiko Kusakabe +8
We have determined the ratios of total to selective extinction in the near-infrared bands (J, H, Ks) toward the Galactic center from the observations of the region |l| < 2.0deg and…
