We present a nearly complete rapid neutron-capture process (r-process) chemical inventory of the metal-poor ([Fe/H]=-1.46+/-0.10) r-process-enhanced ([Eu/Fe]=+1.32+/-0.08) halo...

We analyze the parsec-scale jet kinematics from 2007 June to 2018 December of a sample of {gamma}-ray bright blazars monitored roughly monthly with the Very Long Baseline Array...

Using the high-cadence lightcurves collected from the FOSSIL survey, rotation periods of 17 small (diameter 1km<D<3km) Hilda asteroids (hereinafter Hildas) were obtained....

We present a catalog of 97 uniformly vetted candidates for quadruple star systems. The candidates were identified in TESS full-frame image data from sectors 1-42 through a...

In the eighth data release (DR8) of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope, more than 318,740 low-resolution stellar spectra with types from B to early F...

We provide a database of transit times and updated ephemerides for 382 planets based on data from the NASA Transiting Exoplanet Survey Satellite (TESS) and previously reported...

The Sloan Extension for Galactic Understanding and Exploration 2 (SEGUE-2) obtained 128,288 low-resolution spectra (R~1800) of 118,958 unique stars in the first year of the...

We have surveyed the complete extent of Leo A, which is an apparently isolated Local Group dwarf irregular galaxy, in B, V, R, I (the Johnson-Cousins system), and NA656...

We present observations of the carbon-rich protoplanetary nebula CRL2688 made with the Institut de Radioastronomie Millimetrique 30m telescope in the 3 and 2mm bands. In total,...

Measuring the redshift of active galactic nuclei (AGNs) requires the use of time-consuming and expensive spectroscopic analysis. However, obtaining redshift measurements of AGNs...

There is a complex inclination structure present in the trans-Neptunian object (TNO) orbital distribution in the main classical-belt region (between orbital semimajor axes of 39...

The CNIa0.02 project aims to collect a complete, nearby sample of Type Ia supernovae (SNe Ia) light curves, and the SNe are volume-limited with host-galaxy redshifts...

Pulsating stars in eclipsing binaries are very important for understanding the structure of stellar interiors through asteroseismology because their absolute parameters such as...

Hot subdwarf stars are a particular type of star that is crucial for studying binary evolution and atmospheric diffusion processes. In recent years, identifying hot subdwarfs by...

The Hard X-ray Modulation Telescope (Insight-HXMT) is China's first X-ray astronomy satellite. It was launched on 2017 June 15. The anticoincidence CsI detectors of the High...

In fulfilling the aims of the planetary and asteroseismic research missions, such as that of the NASA Transiting Exoplanet Survey Satellite (TESS) space telescope, accurate...

Virgo is the nearest galaxy cluster; it is thus ideal for studies of galaxy evolution in dense environments in the local universe. It is embedded in a complex filamentary...

We present a near-complete catalog of the metal-rich population of thermally pulsing asymptotic giant branch (AGB) stars in the northwest quadrant of M31. This metal-rich sample...

We derive a catalog of early-type emission-line stars including 30023 spectra of 25867 stars from LAMOST Data Release 7, in which 4189 have Simbad records. The spectra are...

We present the Infrared Database of Extragalactic Observables from Spitzer (IDEOS), a homogeneous, publicly available, database of 77 fitted mid-infrared observables in the...
