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...

In depth characterization of the planet masses and radii in the LHS1140 planetary system through observations with ESPRESSO and TESS.

We describe a homogeneous catalog compilation of common proper motion stars based on GaiaDR2. A preliminary list of all pairs of stars within the radius of 100pc around the Sun...

Combining data from Gaia DR2, SDSS DR14, and LAMOST DR6, we update the fit to model of the properties of the stellar stream GD-1 and find that it has an age of ~13Gyr, [Fe/H] of...

V506 Oph was observed spectroscopically with two different instruments. Between 2010 May and 2017 February, we monitored the binary with the Center for Astrophysics Harvard...

Spectra of the companion to PSR J1306-40 were obtained using SOAR/Goodman from 2017 July 11 to 2018 June 9. The spectra covered a wavelength range of ~5485-6740{AA}. Besides,...

We acquired spectra with CARMENES (Quirrenbach et al., 2014, in Proc. SPIE, Vol. 9147, Ground-based and Airborne Instrumentation for Astronomy V, 91471F), a high-resolution...

High-resolution follow-up spectroscopy of the TESS planet candidates is arranged by the TESS follow-up programme (TFOP), "Precise Radial Velocities" SG4 subgroup. We observed GJ...

NTT-EFOSC2 photometry of the central star of PN G283.7-05.1 in B, V, R and i-bands. VLT-FORS2 Heliocentric radial velocity measurements of the hot and cool components of the...

We have spectroscopically identified 1999 DBWDs in the SDSS DR12 and DR14, including 58 newly identified objects, using ML, i.e., LASSO and SVM. A total of 176 DB objects from...

We analyse spectra from the FEROS, HARPS, ELODIE, SOPHIE, UVES, and CAFE spectrographs. We refer to section 2 for a detailed description of the observations and data analysis.

Here, we present 95 RV measurements of runaway stars AE Aur and iota Ori, taken between 2016 and 2018 at the University Observatory Jena with the Echelle spectrograph FLECHAS.

Time-series photometry of ETHOS 1 in the i band, acquired using the MEROPE camera mounted on the 1.2-m Flemish Mercator Telescope between 2009 August 24 and September 4, was...

The discovery and analysis of the system CzeV1731 represents a rare configuration of a 2+2 quadruple star system containing two eclipsing binaries, the third system of its kind...

Photometry collected with the STELLA telescope; radial velocities and stellar activity diagnostics extracted from HARPS-N spectra.

The 20 tables, which conform Appendix C in our paper, show the results of our analysis and the final selections of candidate members for each cluster, as well as the lists of...

The observations of pi Men with ESPRESSO (using the instrument in single Unit Telescope mode with a median resolving power R=138000 over the 378.2 and 788.7nm wavelength range)...

The Kepler satellite observed our program target V404 Lyr in long-cadence mode almost continuously from Q0 to Q17 (May 2009 - Apr 2013). In this work, we used the simple...

Since 2015 a radial velocity monitoring campaign is going on at the University Observatory Jena. The aim of this project is to obtain radial velocity measurements of selected...

Stellar properties of a parent sample of nearby Sun-like stars with parallaxes greater than 20mas used in the study. For each star, the name, spectral type, right ascension and...
