Extreme Lithium Depletion in Solar Twins: Challenging Non-Standard Mixing Models
Isabelle Winnick, Jhon Yana Galarza, Henrique Reggiani +12
Lithium (Li) is a powerful tracer of stellar mixing, gradually depleted in solar twins by non-standard transport below the convective zone. Here, we identify six new solar twins wi…

A systematic method to identify runaways from star clusters produced from single-binary interactions: A case study of M67
A. Herrera-Urquieta, N. Leigh, J. Pinto +9
One hypothesis for runaway stars (RSs) is that they are ejected from star clusters with high velocities relative to the cluster center-of-mass motion. There are two competing mecha…

The S-PLUS Fornax Project (S+FP): A first 12-band glimpse of the Fornax galaxy cluster
A. V. Smith Castelli, A. Cortesi, R. F. Haack +40
The Fornax galaxy cluster is the richest nearby (D ~ 20 Mpc) galaxy association in the southern sky. As such, it provides a wealth of oportunities to elucidate on the processes whe…
