Discovery and Characterization of the TOI-4468 Planetary System: A Transiting Hot Jupiter With a Lone Nearby Outer Companion

Joseph R. Livesey, Benjamin J. Hord, Juliette Becker +28

We report the discovery of two planets, a hot Jupiter and a nearby outer sub-Neptune, orbiting the star TOI-4468. This system is unique among the current exoplanet census in that i…

TOI-7169 b: A Hot Jupiter Transiting a Metal-Poor Star

Joshua D. Simon, Joseph E. Rodriguez, Jhon Yana Galarza +38

Most known planets are found around metal-rich host stars, which has made it difficult to determine whether a lower metallicity limit for planet formation exists and how the proper…

Gaia20fnr: A binary-lens microlensing event with full orbital motion revealed by four space telescopes

M. Wicker, Ł. Wyrzykowski, M. Hundertmark +49

The microlensing event Gaia20fnr is a long-duration, non-caustic-crossing binary-lens event at high Galactic latitude. Triggered by a photometric rise detected by the Gaia space mi…
