Our targets are RGBs located in the central 250 field of the Sextans dSph. We gathered high-resolution (R~20000) spectra of 101 stars in the HR10, HR13, and H14 gratings of the...

The data of the W3-W4-W5 (W345) complexes were collected between fall 2016 and winter 2017. The survey is made possible through the two Apache Point Observatory (APO) Galactic...

The tables contain the astrophysical data of more than 200 Herbig Ae/Be stars as listed in Vioque et al. (2018A&A...620A.128V, Cat. J/A+A/620/A128), and for which accretion...

We obtain high-resolution spectra (R=110000 and a slit width of 0.5mm), covering the wavelength range of 3730-9989{AA}, for a sample of 12 stars, using the 2.4m Lick Automated...

We collected spectra using one night of observation with the Near Infrared Spectrograph (NIRSPEC) on the 10m Keck II Telescope located on the summit of Maunakea in Hawaii, and...

The IRTF spectral library (Cushing et al., 2005ApJ...623.1115C; Rayner et al., 2009ApJS..185..289R) contains flux calibrated spectra of about 200 objects, with a typical...

In this paper, we extend our previous search of CIV NALs released in Papers I (Chen et al., 2014, Cat. J/ApJS/210/7) and II (Chen et al., 2014, Cat. J/ApJS/215/12) to spectral...

Gaia DR2 data, 2MASS photometry, EW(Li)s, masses, ages, UVW velocities, RVs, MG matches from the chi-squared analysis and from the BANYAN{Sigma} code, and the source survey...

We have studied the correlation between the NAL variability and the continuum variability using a sample of two-epoch SDSS spectra of 40 quasars with 52 variable...

A particularly large volume of the STIS echelle spectra on the Hubble Space Telescope (HST) cover the wavelength region from 1170 to 1372{AA}, which includes transitions of OI,...

During a study of circumstellar disks in Upper Sco, Luhman & Mamajek (2012, J/ApJ/758/31) compiled a list of known members of the association. That list contained 863...

We have investigated the star-forming environment of the less studied FUor V582 Aur. Based on H{alpha} emission detected in slitless spectra and infrared excesses revealed by...

We show that the equivalent widths of the well-known interstellar CaII H and K lines can be used to determine the distances to OB stars in our Galaxy. The equivalent widths,...

We present H{alpha}-derived SFRs for three z~0.75 galaxy clusters. Our 1{sigma} flux limit corresponds to a star formation rate (SFR) of 0.10-0.24h^-2^100_M{Sun}/yr, and our...

Thanks to the INfrared Spectra of Young Nebulous Clusters (IN-SYNC) program, more than 3000 stars in NGC 1333, IC 348, and the Orion A molecular cloud have been observed with...

The SDSS is a comprehensive imaging and spectroscopic survey using a dedicated 2.5m telescope located at Apache Point Observatory to image over 10000deg^2^ of sky and to perform...

We obtained spectra for 614 KISS objects at KPNO, using the 2.1m telescope and the 3.5m WIYN telescope. The observations were carried out over five seasons in 1998 (WIYN), 1999...

The observations were carried out on the night of 2004 November 30 at the W. M. Keck Observatory under photometric conditions and a typical seeing of 1.1".

We present results from optical spectrophotometry of 19 of the 25 lobe-dominated quasars in the 3CR complete sample. The optical spectra were obtained with the Hale 5m telescope...

We investigate the optical and MIR spectral properties of a sample of 82 Type 1 AGNs. Additionally, to check the results based on the narrow lines (which are superposed with...
