Asteroseismology of the Nearby K-Dwarf Draconis using the Keck Planet Finder and TESS
Marc Hon, Daniel Huber, Yaguang Li +76
Asteroseismology of dwarf stars cooler than the Sun is very challenging due to the low amplitudes and rapid timescales of oscillations. Here, we present the asteroseismic detection…
A Data-driven Spectral Model of Main Sequence Stars in Gaia DR3
Isabel Angelo, Megan Bedell, Erik Petigura +1
Precise spectroscopic classification of planet hosts is an important tool of exoplanet research at both the population and individual system level. In the era of large-scale survey…
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…
TOI-1055 b: Neptunian planet characterised with HARPS, TESS, and CHEOPS
A. Bonfanti, D. Gandolfi, J. A. Egger +89
TOI-1055 is a Sun-like star known to host a transiting Neptune-sized planet on a 17.5-day orbit (TOI-1055 b). Radial velocity (RV) analyses carried out by two independent groups us…
The Solar Twin Planet Search. V. Close-in, low-mass planet candidates and evidence of planet accretion in the solar twin HIP 68468
Jorge Melendez, Megan Bedell, Jacob L. Bean +14
[Methods]. We obtained high-precision radial velocities with HARPS on the ESO 3.6 m telescope and determined precise stellar elemental abundances (~0.01 dex) using MIKE spectra on…
