A planetary-mass candidate imaged in the Young Suns Exoplanet Survey

Pengyu Liu, Matthew A. Kenworthy, Beth A. Biller +26

Directly imaged exoplanets in wide orbits challenge current gas giant formation theories. They need to form quickly and acquire enough material before the disk dissipates, which ca…

Homomesies on permutations -- an analysis of maps and statistics in the FindStat database

Jennifer Elder, Nadia Lafrenière, Erin McNicholas +2

In this paper, we perform a systematic study of permutation statistics and bijective maps on permutations in which we identify and prove 122 instances of the homomesy phenomenon. H…

Unveiling wide-orbit companions to K-type stars in Sco-Cen with Gaia EDR3

Alexander J. Bohn, Christian Ginski, Matthew A. Kenworthy +12

Abbreviated. We aim to identify new low-mass companions to young stars using the astrometric measurements provided by the Gaia space mission and complementary VLT/SPHERE data. We i…

Discovery of a directly imaged planet to the young solar analog YSES 2

Alexander J. Bohn, Christian Ginski, Matthew A. Kenworthy +8

Abbreviated. By selecting stars with similar ages and masses, the Young Suns Exoplanet Survey (YSES) aims to detect and characterize planetary-mass companions to solar-type host st…

Two Directly Imaged, Wide-orbit Giant Planets around the Young, Solar Analog TYC 8998-760-1

Alexander J. Bohn, Matthew A. Kenworthy, Christian Ginski +9

Even though tens of directly imaged companions have been discovered in the past decades, the number of directly confirmed multiplanet systems is still small. Dynamical analysis of…

The Young Suns Exoplanet Survey: Detection of a wide orbit planetary mass companion to a solar-type Sco-Cen member

A. J. Bohn, M. A. Kenworthy, C. Ginski +9

The Young Suns Exoplanet Survey (YSES) consists of a homogeneous sample of 70 young, solar-mass stars located in the Lower Centaurus-Crux subgroup of the Scorpius-Centaurus associa…
