The GAPS programme at TNG XLIX. TOI-5398, the youngest compact multi-planet system composed of an inner sub-Neptune and an outer warm Saturn

G. Mantovan, L. Malavolta, S. Desidera +68

Short-period giant planets are frequently found to be solitary compared to other classes of exoplanets. Small inner companions to giant planets with 15 days are known…

Cold Jupiters and improved masses in 38 Kepler and K2 small planet systems from 3661 HARPS-N radial velocities. No excess of cold Jupiters in small planet systems

A. S. Bonomo, X. Dumusque, A. Massa +31

The exoplanet population characterized by relatively short orbital periods ( d) around solar-type stars is dominated by super-Earths and sub-Neptunes. However, these planets…

Transit Timing Variations for AU Microscopii b & c

Justin M. Wittrock, Stefan Dreizler, Michael A. Reefe +42

We explore the transit timing variations (TTVs) of the young (22 Myr) nearby AU Mic planetary system. For AU Mic b, we introduce three Spitzer (4.5 m) transits, five TESS transi…

A Second Planet Transiting LTT 1445A and a Determination of the Masses of Both Worlds

J. G. Winters, R. Cloutier, A. A. Medina +79

LTT 1445 is a hierarchical triple M-dwarf star system located at a distance of 6.86 parsecs. The primary star LTT 1445A (0.257 M_Sun) is known to host the transiting planet LTT 144…

Minimum Orbital Periods of H-Rich Bodies

S. Rappaport, A. Vanderburg, J. Schwab +1

In this work we derive the minimum allowed orbital periods of H-rich bodies ranging in mass from Saturn's mass to 1 , emphasizing gas giants and brown dwarfs over the ra…

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…

Tidally Trapped Pulsations in a close binary star system discovered by TESS

G. Handler, D. W. Kurtz, S. A. Rappaport +12

It has long been suspected that tidal forces in close binary stars could modify the orientation of the pulsation axis of the constituent stars. Such stars have been searched for, b…

Eclipsing Spotted Giant Star With K2 and Historical Photometry

K. Oláh, S. Rappaport, T. Borkovits +15

Context. Stars can maintain their observable magnetic activity from the PMS to the tip of the red giant branch. However, the number of known active giants is much lower than active…

Occultations from an active accretion disk in a 72 day detached post-Algol system detected by K2

G. Zhou, S. Rappaport, L. Nelson +28

Disks in binary systems can cause exotic eclipsing events. MWC 882 (BD-22 4376, EPIC 225300403) is such a disk-eclipsing system identified from observations during Campaign 11 of t…

The First Post-Kepler Brightness Dips of KIC 8462852

Tabetha S. Boyajian, Roi Alonso, Alex Ammerman +203

We present a photometric detection of the first brightness dips of the unique variable star KIC 8462852 since the end of the Kepler space mission in 2013 May. Our regular photometr…

WD 1145+017: Optical Activity During 2016-2017 and Limits on the X-Ray Flux

S. Rappaport, B. L. Gary, A. Vanderburg +3

WD 1145+017 was observed from 2016 November through 2017 June for the purpose of further characterizing the transit behavior of the dusty debris clouds orbiting this white dwarf. T…
