The Bochum Galactic Disk Survey is a project to monitor the stellar content of the Galactic disk in a 6 degree wide stripe centered on the Galactic plane. The data has been...

The Robotic Bochum Twin Telescope (RoBoTT) operated from December 2008 to September 2019 at the Universitaetssternwarte Bochum near Cerro Armazones in the Chilean Atacama...

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,...

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...

Extracted sources from the Bochum Galactic Disk Survey. We provide median photometry in U, B, V, z, r, and i broadbands as well as the narrow bands OIII,...

Median photometry in U, B, V, z, r, and i broadbands as well as the narrow bands OIII, NB, Halpha and SII for particular objects; all measurements have...

This service exposes the light curves of stars produced by the Bochum Galactic Disk Survey DR2; several million light curves are provided in the SDSS i and r bands. The...

We present medium resolution near-infrared spectral measurements of the carbon monoxide (CO) and the cyano radical (CN) features in 12 Galactic classical Cepheids. The pulsation...

The vast majority of stars in the nearby stellar neighborhood are M dwarfs. Their low masses and luminosities result in slow rates of nuclear evolution and minimal changes to...

Magnetic hot stars refer to stars that have effective temperatures approximately in the range from 7000-50000K, and with large-scale globally organized magnetic fields. These...

We present the deepest color-magnitude diagram (CMD) for NGC 205 in the F606W (~V) and F814W (~I) filters. Our archival Hubble Space Telescope/Advanced Camera for Surveys field...

Stellar rotation, a key factor influencing stellar structure and evolution, also drives magnetic activity, which is manifested as spots or flares on stellar surface. Here, we...

We present the OGLE collection of delta Scuti stars in the Large Magellanic Cloud and in its foreground. Our dataset encompasses a total of 15256 objects, constituting the...

This file contains Galactic stars known or suspected to be variable. It lists all stars that have an entry in the AAVSO International Variable Star Index (VSX;...

We present results from a systematic infrared (IR) census of R Coronae Borealis (RCB) stars in the Milky Way, using data from the Palomar Gattini IR (PGIR) survey. RCB stars are...

NGC 7419 is a young open cluster notable for hosting five red supergiants and a high abundance of Classical Be (CBe) stars. CBe stars are main-sequence non-supergiant B-type...

The lowest mass at which the third dredge-up (TDU) occurs for thermally pulsing asymptotic giant branch (TP-AGB) stars remains a key uncertainty in detailed stellar models....

Asymptotic giant branch (AGB) stars are the primary source of dust and complex molecules in the interstellar medium. The determination of outflow parameters is often hindered by...

Stellar variability and transient events provide critical insights into many areas of astrophysics. Progress in these fields has been accelerated by high-precision space-based...

Using high-precision astrometric data from Gaia DR3 and updated systemic velocities from the literature, the kinematical properties of cataclysmic variables (CVs) were...
