Looking for Companionship: Radial Velocity Follow-Up of Lithium-Rich Giants with ESPRESSO

Maryum Sayeed, Andrew R. Casey, Benjamin T. Montet +4

Lithium-rich red giants have been a long-standing mystery in stellar astrophysics. A leading theory to explain these chemically peculiar and rare objects is interactions with a clo…

Spectroscopic Follow-up of Young High- Dwarf Star Candidates: Still Likely Genuinely Young

Yuxi Lu, Catherine Manea, Maryum Sayeed +9

The question of whether genuinely young high- stars exist has been discussed for over a decade since their discovery from asteroseismology of giant stars as it is challenging t…

Probing Binary Architectures of Lithium-Rich Giants in GALAH with COSMIC and Stellar Models

Maryum Sayeed, Selina Yang, Giulia Cinquegrana +5

Surface lithium is depleted when a star goes through the first dredge-up phase, yet of red giants are found to be Li-rich. The formation mechanism for these remains uncertain…

Exoplanet Occurrence Rate with Age for FGK Stars in Kepler

Maryum Sayeed, Ruth Angus, Travis Berger +5

We measure exoplanet occurrence rate as a function of isochrone and gyrochronology ages using confirmed and candidate planets identified in Q1-17 DR25 Kepler data. We employ Kepler…
