Giant Planets and Eccentric Orbits Are Common Around Galactic Thick Disc Stars

Thiago Ferreira, Jhon Yana Galarza, Henrique Reggiani +15

Planet formation in the Galactic thick disc is expected to be inefficient---low solid reservoirs, short disc lifetimes, and harsh irradiation environments should conspire to inhibi…

HIP 8522: A Puzzling Young Solar Twin with the Lowest Detected Lithium

Jhon Yana Galarza, Diego Lorenzo-Oliveira, Thiago Ferreira +8

We present HIP 8522, a young solar twin with the lowest detected lithium, potentially a field blue straggler or the result of episodic early accretion. Its stellar parameters ($T_{…

Exploring the photometric variability of ultra-cool dwarfs with TESS

Romina P. Petrucci, Yilen Gómez Maqueo Chew, Emiliano Jofré +2

We present a photometric characterization of 208 ultra-cool dwarfs (UCDs) with spectral types between M4 and L4, from 20-second and 2-minute cadence TESS light curves. We determine…

Are Am stars and hot-Jupiter planets related?

C. Saffe, J. Alacoria, P. Miquelarena +8

Am stars are often components of short-period binary systems, where tidal interactions would result in low rotational velocities and help to develop the chemical peculiarities obse…

A compositional link between rocky exoplanets and their host stars

Vardan Adibekyan, Caroline Dorn, Sérgio G. Sousa +17

Stars and planets both form by accreting material from a surrounding disk. Because they grow from the same material, theory predicts that there should be a relationship between the…

A Bright Short Period M-M Eclipsing Binary from the KELT Survey: Magnetic Activity and the Mass-Radius Relationship for M-dwarfs

Jack B. Lubin, Joseph E. Rodriguez, George Zhou +26

We report the discovery of KELT J041621-620046, a moderately bright (J10.2) M dwarf eclipsing binary system at a distance of 393 pc. KELT J041621-620046 was first identi…
