Radial velocities for 7 cataclysmic variables
We report spectroscopic observations of seven bright southern cataclysmic variable stars, collected on a single two-week observing run using the 1.9m Radcliffe telescope at the... -
RR Lyrae stars in Galactic Globular Clusters
We present a comprehensive catalog of 2824 RR Lyrae stars (RRLs) residing in 115 Galactic globular clusters (GCs). Our catalog includes 1594 fundamental- mode (RRab), 824... -
BL Her stars Gaia PL relation
In the era of the Hubble tension, it is crucial to obtain a precise calibration of the period-luminosity (PL) relations of classical pulsators. Type II Cepheids (T2Cs; often... -
Parameteres for 88 giant variable star candidates
We present the analysis of 510 light curves in V and I bands of 255 giant stars in the globular cluster NGC-3201. Our aim is to expand the sample of new types of variables... -
Field RR Lyrae stars RV and pulsation models
The application of the Parallax of Pulsation (PoP) technique to determine the distances of pulsating stars implies the use of a scaling parameter, the projection factor... -
Infrared LC and spectrum of Scutum X-1 system
The symbiotic X-ray binary Sct X-1 was suggested to be the first known neutron star accreting from a red supergiant companion. Although known for nearly 50yr, detailed... -
V838 Cyg; O-C, amplitude & Fourier coeff modulations
Noting the weakest modulation and relatively high metal abundance of the Ab-type RR-Lyrae star V838Cyg, we collected the photometric data of this star from several sky surveys... -
Spatiotemporal technosignature candidate targets
Spatiotemporal techniques for signal coordination with actively transmitting extraterrestrial civilizations, without the need for prior communication, can constrain... -
Known exoplanet hosts parameters with TESS
Both direct and indirect methods of exoplanet detection rely upon detailed knowledge of the potential host stars. Such stellar characterization allows for accurate extraction of... -
Spot modeling of V1298 Tau using SpotCCF tool
The intrinsic variability due to the magnetic activity of young active stars is one of the main challenges in detecting and characterising exoplanets. The stellar activity is... -
Bochum Galactic Disk Survey (BGDS) images
The Bochum Galactic Disk Survey is an ongoing project to monitor the stellar content of the Galactic disk in a 6 degree wide stripe centered on the Galactic plane. The data has... -
BGDS Mean Photometry Cone Search
Extracted sources from the Bochum Galactic Disk Survey. We provide mean photometry in U, B, V, z, r, and i bands. Note that sources in different bands are not matched. Also,... -
Bochum Galactic Disk Survey (BGDS) light curves
This service exposes the light curves of stars produced by the Bochum Galactic Disk Survey; several million light curves are provided in the SDSS i and r bands. The lightcurves... -
AAVSO Photometric All Sky Survey (APASS) DR10
AAVSO Photometric All-Sky Survey (APASS), underway since 2010, covers the entire sky from 7.5 < V < 16.5 magnitude, and in the BVugrizY bandpasses. A northern and a...
