DESI DR1 redshift catalog
In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving... -
BLOeM. Physical properties of OB stars
We aim to determine the physical properties of OB stars from the multi-epoch Binarity at LOw Metallicity (BLOeM) spectroscopic survey of the Small Magellanic Cloud using the... -
O'Connell effect in contact binaries. I.
Asymmetries between the two maxima of the light curves of contact binaries, known as the O'Connell effect, have been identified using the All Sky Automated Survey, All-Sky... -
Kinematics of YSOs from Gaia DR3 and APOGEE
Based on the Gaia Data Release 3 and APOGEE data sets, we investigate the kinematic differences between young stellar objects (YSOs) and their parent clouds in five nearby... -
Finding galaxy clusters with machine learning
Building a comprehensive catalog of galaxy clusters is a fundamental task for studies on structure formation and galaxy evolution. In this paper, we present Cluster Optical... -
Blue horizontal-branch stars from LAMOST
Blue horizontal-branch (BHB) stars are crucial for studying the structure of the Galactic halo. Accurate atmospheric parameters of BHB stars are essential for investigating the... -
H-poor type IIb SN 2020bio LCs & spectra
We present photometric and spectroscopic observations of SN 2020bio, a double-peaked Type IIb supernova (SN) discovered within a day of explosion, primarily obtained by Las... -
Swift/UVOT and ground-based telescope LCs of Mrk 335
UV and optical continuum reverberation mapping is a powerful tool for probing the accretion disk and inner broad-line region. However, recent reverberation mapping campaigns in... -
HST/WFC3 obs. of the Fireworks galaxy (NGC 6946)
The nearby face-on star-forming spiral galaxy NGC 6946 is known as the Fireworks Galaxy due to its hosting an unusually large number of supernovae. We analyze its resolved... -
Cluster parameters, masses, and radii from Gaia DR3
In the era of a data-driven landscape, the development of an efficient and interpretable method has become a pivotal tool for robustly identifying memberships of clusters. We... -
Radial velocities of TOI-1266 from MAROON-X
We present an analysis of 126 new radial velocity measurements from the MAROON-X spectrograph to investigate the TOI-1266 system, which hosts two known transiting sub-Neptunes... -
Radial velocity curves of Gaia-4 and Gaia-5
Gaia astrometry of nearby stars is precise enough to detect the tiny displacements induced by substellar companions, but radial velocity (RV) data are needed for definitive... -
Tidal Tails of Nearby Open Clusters. II
Recent studies using Gaia data have reported tidal tail detections for tens to hundreds of open clusters. However, a comprehensive assessment of the reliability and completeness... -
AMBRE/FEROS catalogue of line-broadening velocities
Stellar rotation is a fundamental parameter in studies of the formation and evolution of stars. However, large homogeneous catalogues of rotational velocities derived from... -
Penellope VII. Accretion luminosity
The accretion luminosity (Lacc) in young, low-mass stars is crucial for understanding stellar formation. However, obtaining direct measurements is often hindered by limited... -
Optical photometry of SN 2020aeuh
Identifying the progenitors of thermonuclear supernovae (Type Ia supernovae; SNe Ia) remains a key objective in contemporary astronomy. The rare subclass of SNe Ia-CSM that... -
NGC 5634 variable stars light curves
We present new time-series CCD VR photometry of the globular cluster NGC 5634. We aim to use the known RR Lyrae stars, members of the cluster, as indicators of mean metallicity... -
TIC star magnetic activity with LAMOST DR10 MRS sp.
A combination of spectroscopic and photometric observations provides an excellent data sample for studying stellar chromospheric activity. We have combined LAMOST... -
Abundances of member stars of the Sextans dSph
We present the stellar parameters and chemical abundances of 30 elements for five stars located at large radii (3.5-10.7 times the half-light radius) in the Sextans dwarf... -
Type IIP supernova SN 2018gj follow-up obs.
We present an extensive, panchromatic photometric (UV, optical, and near-IR) and low-resolution optical spectroscopic coverage of a Type IIP supernova SN 2018gj that occurred on...
