Tidally perturbed pulsations in OO Dra
Niveditha Parthasarathy, Mikhail Kovalev, Randa Asa'd
We perform a pulsation analysis of OO Dra using Light Curve data from TESS and present the first identification of six dipole modes as doublets from the primary star in OO Dra. The…
Semi-empirical versus Theoretical Stellar Population Models: a comparison with Star Clusters
Randa Asad, Paula R. T. Coelho, Johina M. John +3
Stellar population synthesis (SPS) models are a key tool for deriving the age, metallicity, radial velocity and reddening of star clusters from their integrated spectra. Using a sa…
Search for spectroscopic binaries using rotational velocities in five open clusters observed by ESO
Mikhail Kovalev, Mariyam Ahmed, Randa Asa'd
In this paper we detect double-lined spectroscopic binaries (SB2) in five open clusters: NGC 2243, NGC 2420, NGC 3532, NGC 6253 and NGC 6705 (M 11) using a method based on high val…
Searching for Multiple Populations in the Integrated Light of the Young and Extremely Massive Clusters in the Merger Remnant NGC~7252
Nate Bastian, Carmela Lardo, Christopher Usher +8
Recent work has shown that the properties of multiple populations within massive stellar clusters (i.e., in the extent of their abundance variations as well as the fraction of star…
