Spectroscopically Selected Halo K Giants
The catalog results from a survey for distant Field K giants in the Galactic halo made for purposes of locating a chemically and kinematically unbiased sample out to about 25... -
Equivalent widths of thick-disk red giants
The atmospheric parameters and elemental abundances for ten thick-disk red giants have been determined from high-resolution spectra by the method of model stellar atmospheres.... -
Equivalent widths of 14 red giants
The results of a comparative analysis of the elemental abundances in the atmospheres of 14 red giants with high Galactic space velocities are presented. For almost all of the... -
Tycho-2 red giant branch and carbon stars
Based on multicolor photometry from the 2MASS and Tycho-2 catalogues, we have produced a sample of 38368 branch red giants that has less than 1% of admixtures and is complete... -
Red giant clump in the Tycho-2 catalog
The Tycho-2 proper motions and Tycho-2 and 2MASS photometry are used to select 97348 red giant clump (RGC) stars. The interstellar extinction and photometric distance are... -
Stellar parameters and abundances of 99 giants
We present basic stellar parameters of 99 late-type G giants based on high-resolution spectra obtained by the High Dispersion Spectrograph attached to Subaru Telescope. These... -
SiO maser survey off the Galactic Plane
A group of Mira variables in the solar neighborhood shows unusual spatial motion in the Galaxy. To study this motion on a much larger scale in the Galaxy, we newly surveyed 134... -
SiO and H2O masers in Stephenson 2 cluster
We present the results of radio observations of red supergiants in a star cluster, Stephenson (1990AJ.....99.1867S)'s #2 (Cl Stephenson 2), and of candidates for red supergiants... -
Late-G giants abundances
Towards clarifying the properties of late-G giants, for which we are currently conducting a planet-search project at Okayama Astrophysical Observatory, an extensive... -
M giants in Cassiopeia
Coordinates and identifications for M-type stars in Cassiopeia Cone search capability for table J/PASJ/33/107/table (Catalog of M-, C- and S-type stars) -
K giant stars along Sagittarius streams
The Large Sky-Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 3 provided 341 691 K giant stars with stellar parameters. Based on the models of Law &... -
M-giant star candidates in LAMOST DR 1
We perform a discrimination procedure with the spectral index diagram of TiO_5_ and CaH_2_+CaH_3_ to separate M giants from M dwarfs. Using the M giant spectra identified from... -
BVRI light curves of some cool giant stars
We examine Johnson BV and Cousins RI photometry of the cool giant stars HR 1105, HD 35155, HR 4088, TU CVn, IT Vir, and HR 7442, that the first author obtained with the Four... -
Galactic post-AGB stars in Gaia DR3
This paper presents the first census of Galactic post-asymptotic Giant Branch stars in the HR diagram. We combined Gaia DR3 parallax-based distances with extinction corrected... -
Lithium-rich stars in the GALAH survey DR3
We investigate the properties of 1262 red giant stars with high photospheric abundances of lithium observed by the GALAH and K2-HERMES surveys, and discuss them in the context... -
The extended MILES library
Extragalactic astronomy and stellar astrophysics are intrinsically related. In fact, the determination of important galaxy properties such as stellar masses, star formation... -
Giant stars in TESS continuous viewing zones
The NASA Transiting Exoplanet Survey Satellite (NASA-TESS) mission presents a treasure trove for understanding the stars it observes and the Milky Way, in which they reside. We... -
Temperature and metallicity scale of cool giants
We present here quantitative diagnostic tools for cool giants that employ low-resolution near-infrared spectroscopy in the K band for stellar population studies. In this study,... -
Stars in the Sagittarius stream
We assemble a catalogue of candidate Sagittarius stream members with 5D and 6D phase-space information, using astrometric data from Gaia DR2, distances estimated from RR Lyrae... -
Gaia DR2 giants in the Galactic dust I
We consider a complete sample of 101810 giants with Gaia Data Realease 2 (DR2) parallaxes {varpi} within the red clump domain of the Hertzsprung-Russell diagram in the space...
