The H-alpha emission star BD + 24 deg 676, formerly classified as a T Tauri star and more recently as a Herbig Ae star, has been observed at moderately high...
The System Parameters of the Polars MR SER and ST LMi
We obtain the Na I lambda 8183,8195 absorption line radial velocity curves for the polars ST LMi and MR Ser, from which we find the semi-amplitudes to be Kabs...
The Tarantula survey is an ESO Large Programme which has obtained multi-epochs spectroscopy of over 800 massive stars in the 30 Dor region in the Large...
Unraveling the Complexity of Dwarf Galaxy Dynamics: A Study of Binary Orbital Motions
We investigate the impact of binary orbital motions on the dynamical modeling of dwarf galaxies with intrinsic line-of-sight velocity dispersions ( ${\sigma }_{...
Volumetric Rates of Luminous Red Novae and Intermediate-luminosity Red Transients with the Zwicky Transient Facility
Luminous red novae (LRNe) are transients characterized by low luminosities and expansion velocities, and they are associated with mergers or common-envelope...
We created the APOGEE-GALEX-Gaia catalog to study white dwarf (WD) binaries. This database aims to create a minimally biased sample of WD binary systems...
