In the Trenches of the solar-stellar connection. VII.
The Wilson-Bappu effect (WBE) is a remarkable correlation between the width of the chromospheric emission core of the CaII 3934{AA} K line and stellar absolute visual magnitude... -
Am stars selected in LAMOST DR8-DR10
A total of about 21,600 Am candidates were detected with the MKCLASS code based on the low-resolution spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope... -
Stellar sp. libraries in Opt-NIR. I. UVES-POP
We present reprocessed flux-calibrated spectra of 406 stars from the UVES-POP stellar library in the wavelength range 320-1025nm, which can be used for stellar population... -
Low-mass companions to KOIs observed with APOGEE
We report the characterization of 28 low-mass (0.02M_{sun}<=M_2<=0.25M_{sun}_) companions to Kepler objects of interest (KOIs), eight of which were previously designated... -
C^18^O dense cores in Orion A molecular cloud
The mass distribution of dense cores is a potential key to understanding the process of star formation. Applying dendrogram analysis to the CARMA-NRO Orion C^18^O (J=1-0) data,... -
WISE Green Objects massive YSOs in the Gal. plane
Massive young stellar objects (MYSOs) play a crucial role in star formation. Given that MYSOs were previously identified based on the extended structure and the observational... -
The COSMOS2020 catalog
The Cosmic Evolution Survey (COSMOS) has become a cornerstone of extragalactic astronomy. Since the last public catalog in 2015, a wealth of new imaging and spectroscopic data... -
Early-type star stellar rotations in LAMOST MRS. I.
We derive stellar parameters and abundances ("stellar labels") of 40034 late-B and A-type main-sequence stars extracted from the Large Sky Area Multi-Object Fiber Spectroscopic... -
Magellan-TESS Survey (MTS). I. Midsurvey results
Kepler revealed that roughly one-third of Sunlike stars host planets orbiting within 100 days and between the size of Earth and Neptune. How do these planets form, what are they... -
Short period eclipsing binaries from Kepler data
During the primary Kepler mission, between 2009 and 2013, about 150,000 preselected targets were observed with a 29.42 minute long cadence. However, a survey of background stars... -
Surface rotation & activity for Kepler stars. II.
Dark magnetic spots crossing the stellar disk lead to quasiperiodic brightness variations, which allow us to constrain stellar surface rotation and photometric activity. The... -
The Spitzer Kepler Survey (SpiKeS) catalog
The ~200000 targets monitored for photometric variability during the Kepler prime mission include the best-studied group of stars in the sky, due both to the extensive time... -
Compilation of W UMa stars
We present a statistical study of the largest bibliographic compilation of stellar and orbital parameters of W UMa stars derived by light-curve synthesis with Roche models. The... -
A full-sky census of brown dwarfs within 20pc
We present final Spitzer trigonometric parallaxes for 361 L, T, and Y dwarfs. We combine these with prior studies to build a list of 525 known L, T, and Y dwarfs within 20pc of... -
Ages of field stars from white dwarf comp. in Gaia
We analyze 4050 wide binary star systems involving a white dwarf (WD) and usually a main-sequence (MS) star, drawn from the large sample assembled by Tian+ (2020, J/ApJS/246/4).... -
MIR outbursts in nearby SDSS gal. (MIRONG). I.
Optical time-domain astronomy has grown rapidly in the past decade, but the dynamic infrared sky is rarely explored. Aiming to construct a sample of mid-infrared outbursts in... -
ALMA survey of Orion PGCCs (ALMASOP). II. 1.3mm
Planck Galactic Cold Clumps (PGCCs) are considered to be the ideal targets to probe the early phases of star formation. We have conducted a survey of 72 young dense cores inside... -
Late-type contact binaries in CSS DR1
We present the physical parameters of 2335 late-type contact binary (CB) systems extracted from the Catalina Sky Survey (CSS). Our sample was selected from the CSS Data Release... -
Opt. photometry of SMUDGes ultra-diffuse galaxies
We present the first systematic study of the stellar populations of ultra-diffuse galaxies (UDGs) in the field, integrating the large area search and characterization of UDGs by... -
K2 star parameters from Gaia & LAMOST
Previous measurements of stellar properties for K2 stars in the Ecliptic Plane Input Catalog (EPIC) largely relied on photometry and proper motion measurements, with some added...
