Gaia Focused Product Release: Asteroid orbital solution. Properties and assessment
Gaia Collaboration, P. David, F. Mignard +2
Context. We report the exploitation of a sample of epoch astrometry for 157 000 asteroids, the same object in the Gaia Data Release 3, extended over the time coverage planned for t…
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…
HD 183579b: A Warm Sub-Neptune Transiting a Solar Twin Detected by TESS
Tianjun Gan, Megan Bedell, Sharon Xuesong Wang +48
We report the discovery and characterization of a transiting warm sub-Neptune planet around the nearby bright ( mag, mag) solar twin HD 183579, delivered by the Tr…
A faint companion around CrA-9: protoplanet or obscured binary?
V. Christiaens, M. -G. Ubeira-Gabellini, H. Cánovas +16
Understanding how giant planets form requires observational input from directly imaged protoplanets. We used VLT/NACO and VLT/SPHERE to search for companions in the transition disc…
The TOI-763 system: sub-Neptunes orbiting a Sun-like star
M. Fridlund, J. Livingston, D. Gandolfi +51
We report the discovery of a planetary system orbiting TOI-763 (aka CD-39 7945), a , high proper motion G-type dwarf star that was photometrically monitored by the TESS spa…
The GALAH Survey: Using Galactic Archaeology to Refine our Knowledge of TESS Target Stars
Jake T. Clark, Mathieu Clerte, Natalie R. Hinkel +29
An unprecedented number of exoplanets are being discovered by the Transiting Exoplanet Survey Satellite (TESS). Determining the orbital parameters of these exoplanets, and especial…
K2-HERMES II. Planet-candidate properties from K2 Campaigns 1-13
Robert A. Wittenmyer, Jake T. Clark, Sanjib Sharma +22
Accurate and precise radius estimates of transiting exoplanets are critical for understanding their compositions and formation mechanisms. To know the planet, we must know the host…
The multi-planet system TOI-421 -- A warm Neptune and a super puffy mini-Neptune transiting a G9 V star in a visual binary
Ilaria Carleo, Davide Gandolfi, Oscar Barragán +110
We report the discovery of a warm Neptune and a hot sub-Neptune transiting TOI-421 (BD-14 1137, TIC 94986319), a bright (V=9.9) G9 dwarf star in a visual binary system observed by…
Three planets transiting the evolved star EPIC 249893012: a hot 8.8-M super-Earth and two warm 14.7 and 10.2-M sub-Neptunes
D. Hidalgo, E. Pallé, R. Alonso +57
We report the discovery of a new planetary system with three transiting planets, one super-Earth and two sub-Neptunes, that orbit EPIC\,249893012, a G8\,IV-V evolved star ($M_\star…
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…
