The Extreme Stellar-Signals Project III. Combining Solar Data from HARPS, HARPS-N, EXPRES, and NEID
Lily L. Zhao, Xavier Dumusque, Eric B. Ford +37
We present an analysis of Sun-as-a-star observations from four different high-resolution, stabilized spectrographs -- HARPS, HARPS-N, EXPRES, and NEID. With simultaneous observatio…
Many Roads Lead to Lithium: Formation Pathways For Lithium-Rich Red Giants
Maryum Sayeed, Melissa K. Ness, Benjamin T. Montet +8
Stellar models predict that lithium (Li) inside a star is destroyed during the first dredge-up phase, yet 1.2% of red giant stars are Li-rich. We aim to uncover possible origins of…
Joint Modeling of Radial Velocities and Photometry with a Gaussian Process Framework
Quang H. Tran, Megan Bedell, Daniel Foreman-Mackey +1
Developments in the stability of modern spectrographs have led to extremely precise instrumental radial velocity (RV) measurements. For most stars, the detection limit of planetary…
Fishing for Planets: A Comparative Analysis of EPRV Survey Performance in the Presence of Correlated Noise
Arvind F. Gupta, Megan Bedell
With dedicated exoplanet surveys underway for multiple extreme precision radial velocity (EPRV) instruments, the near-future prospects of RV exoplanet science are promising. These…
A Jupiter analogue and a cold Super-Neptune orbiting the solar-twin star HIP 104045
Thiago Ferreira, Jorge Meléndez, Diego Lorenzo-Oliveira +3
We present the discovery of two planets around the solar twin HIP 104045 via radial velocity data obtained with the ESO/HARPS spectrograph as part of the Solar Twin Planet Search o…
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…
