Long-term X-ray Variability of the Symbiotic System RT Cru based on Chandra Spectroscopy
A. Danehkar, M. Karovska, J. J. Drake +1
RT Cru belongs to the rare class of hard X-ray emitting symbiotics, whose origin is not yet fully understood. In this work, we have conducted a detailed spectroscopic analysis of X…
Preliminary Target Selection for the DESI Milky Way Survey (MWS)
Carlos Allende Prieto, Andrew P. Cooper, Arjun Dey +31
The DESI Milky Way Survey (MWS) will observe 8 million stars between mag, supplemented by observations of brighter targets under poor observing conditions. The s…
Li-rich giant stars under scrutiny: Binarity, magnetic activity and the evolutionary status after Gaia DR2
B. F. O. Gonçalves, J. S. da Costa, L. de Almeida +2
We present a study of the evolutionary state of a few lithium-rich giant stars based on the Gaia DR2 parallaxes and photometry. We also investigate the chromospheric activity, the…
Is the gap in the DS Tau disc hiding a planet?
Benedetta Veronesi, Enrico Ragusa, Giuseppe Lodato +6
Recent mm-wavelength surveys performed with the Atacama Large Millimeter Array (ALMA) have revealed protoplanetary discs characterized by rings and gaps. A possible explanation for…
HATS-47b, HATS-48Ab, HATS-49b and HATS-72b: Four Warm Giant Planets Transiting K Dwarfs
J. D. Hartman, Andrés Jordán, D. Bayliss +43
We report the discovery of four transiting giant planets around K dwarfs. The planets HATS-47b, HATS-48Ab, HATS-49b, and HATS-72b have masses of ,…
Investigating Opacity Modifications and Reaction Rate Uncertainties to Resolve the Cepheid Mass Discrepancy
Joyce A. Guzik, Ebraheem Farag, Jakub Ostrowski +4
Cepheid masses derived from pulsations or binary dynamics are generally lower than those derived from stellar evolution models. Recent efforts have been dedicated to investigating…
