Using data from the all-sky Wide-Field Infrared Survey Explorer (WISE) satellite, we made a catalog of over 8000 Galactic HII regions and HII region candidates by searching for...

We present the Red MSX Source survey, the largest statistically selected catalog of young massive protostars and H II regions to date. We outline the construction of the catalog...

We have collated absorption line data toward 3008 stars in order to create a unified database of interstellar column densities. These data have been taken from a number of...

A table is presented that summarizes published absorption line measurements for the high- and intermediate-velocity clouds (HVCs and IVCs). New values are derived for N(HI) in...

Results of an objective prism Schmidt survey are combined with IRAS survey data in order to assess the star-forming activity in the Cepheus Flare, a nearby giant molecular cloud...

Diffuse interstellar bands (DIBs) are broad absorption features associated with interstellar dust and can serve as chemical and kinematic tracers. Conventional measurements of...

We present a low-dispersion period-luminosity relation (PL) based on 154 Cepheids in Messier 33 (M33) with Hubble Space Telescope (HST) photometry from the PHATTER survey. Using...

We construct a sample of 644 carbon-enhanced metal-poor (CEMP) stars with abundance analyses based on moderate- to high-resolution spectroscopic studies. Dynamical parameters...

HI Ly{alpha} (1215.67{AA}) and the OI triplet (1302.17, 1304.86, and 1306.03{AA}) are bright far-ultraviolet (FUV) emission lines that trace the stellar chromosphere....

We present a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric metallicity and distance estimates from our newly calibrated P-{Phi}31-R_21_-[Fe/H]/P-R_21_-[Fe/H]...

Orbital characteristics based on Gaia Early Data Release 3 astrometric parameters are analyzed for ~1700 r-process-enhanced (RPE; [Eu/Fe]>+0.3) metal-poor stars...

We present a table of 215 supernova remnants (SNRs) with distances. New distances are found to SNR G51.26+0.11 of 6.6+/-1.7kpc using HI absorption spectra and to five other SNRs...

We present the results of a density-based clustering analysis of the 6D XYZ Galactic positions and UVW-space velocities of nearby (<=200pc) Gaia Early Data Release 3 stars...

We present the star formation activity around the emission nebula Sh2-112. At a distance of ~2.1kpc, this HII complex, itself 3pc in radius, is illuminated by the massive star...

We present the results from an Atacama Large Millimeter/submillimeter Array (ALMA) 1.3mm continuum and ^12^CO (J=2-1) line survey spread over 10deg^2^ in the Serpens...

We use Gaia DR3 data to study the Collinder 132-Gulliver 21 region via the machine-learning algorithm StarGO and find eight subgroups of stars (ASCC 32, Collinder 132 gp 1-6,...

Close encounters of stars to the Sun could affect life on Earth through gravitational perturbations of comets in the Oort cloud or exposure to ionizing radiation. By integrating...

We present the discovery of 17 double white dwarf (WD) binaries from our ongoing search for extremely low mass (ELM) <0.3M_{sun} WDs, objects that form from binary evolution....

We present optical spectroscopy observations of 145 high-mass pre-main-sequence candidates from the catalog of Vioque et al. (2020, PhD thesis University of Leeds) From these,...

Accretion is one of the defining characteristics of classical T Tauri stars, fueled by the presence of a circumstellar disk comprised of dust and gas. Accretion produces a UV...
