The Sun's chemical peculiarity: disentangling Galactic chemical evolution and planetary engulfment in solar twins

Mia Babatsikos, Fan Liu, Amanda Karakas +5

Recent observational studies have suggested that the Sun may be chemically peculiar relative to the majority of solar twins. Here, we re-analyse high-resolution, high signal-to-noi…

Planets Around Solar Twins/Analogs (PASTA) II: chemical abundances, systematic offsets, and clues to planet formation

Qinghui Sun, Chenyang Ji, Sharon Xuesong Wang +5

Context. Previous studies have suggested that the Sun is relatively depleted in refractory elements compared to other solar twins or analogs, potentially as a result of planet form…

A Compact, Coherent Representation of Stellar Surface Variation in the Spectral Domain

Lily L. Zhao, Megan E. Bedell, David W. Hogg +1

Time-varying inhomogeneities on stellar surfaces constitute one of the largest sources of radial velocity (RV) error for planet detection and characterization. We show that stellar…

gaspery: Optimized Scheduling of Radial Velocity Follow-Up Observations for Active Host Stars

Christopher Lam, Megan Bedell, Lily L. Zhao +2

Radial velocity (RV) follow-up is a critical complement of transiting exoplanet surveys like the Transiting Exoplanet Survey Satellite (TESS ), both for validating discoveries of e…

Planet Hunters TESS V: a planetary system around a binary star, including a mini-Neptune in the habitable zone

Nora L. Eisner, Samuel K. Grunblatt, Oscar Barragán +61

We report on the discovery and validation of a transiting long-period mini-Neptune orbiting a bright (V = 9.0 mag) G dwarf (TOI 4633; R = 1.05 RSun, M = 1.10 MSun). The planet was…

The Sun Remains Relatively Refractory Depleted: Elemental Abundances for 17,412 Gaia RVS Solar Analogs and 50 Planet Hosts

Rayna Rampalli, Melissa K. Ness, Graham H. Edwards +2

The elemental abundances of stars, particularly the refractory elements (e.g., Fe, Si, Mg), play an important role in connecting stars to their planets. Most Sun-like stars do not…
