Spinning up the Surface: Evidence for Planetary Engulfment or Unexpected Angular Momentum Transport?

Shreeya Sushil Shetye

In this paper, we report the potential detection of a nonmonotonic radial rotation profile in a low-mass lower-luminosity giant star. For most low- and intermediate-mass stars, the rotation on the main sequence seems to be close to rigid. As these stars ev ...

VELOcities of CEpheids (VELOCE): I. High-precision radial velocities of Cepheids

Vivien François Bonvin, Mauricio Cruz Reyes, Giordano Viviani, Saniya Khan, Henryka Ewa Netzel, Shreeya Sushil Shetye, Zoi Tzogia Spetsieri

We present the first data release of VELOcities of CEpheids (VELOCE), dedicated to measuring the high-precision radial velocities (RVs) of Galactic classical Cepheids (henceforth, Cepheids). The first data release (VELOCE DR1) comprises 18 225 RV measureme ...

VELOcities of CEpheids (VELOCE): II. Systematic search for spectroscopic binary cepheids

Richard Irving Anderson, Giordano Viviani, Shreeya Sushil Shetye

Classical Cepheids provide valuable insights into the evolution of stellar multiplicity among intermediate-mass stars. Here, we present a systematic investigation of single-lined spectroscopic binaries (SB1s) based on high-precision velocities measured by ...

Barium and related stars, and their white-dwarf companions

Shreeya Sushil Shetye, Pierre North, Conrad Johnston

Barium (Ba) dwarfs and CH subgiants are the less evolved analogues of Ba and CH giants. They are F- to G-type main-sequence stars polluted with heavy elements by their binary companions when the companion was on the asymptotic giant branch (AGB). This comp ...
