A transiting multi-planet system in the 61 million year old association Theia 116

Sydney Vach, George Zhou, Chelsea X. Huang +28

Observing and characterizing young planetary systems can aid in unveiling the evolutionary mechanisms that sculpt the mature exoplanet population. As an all-sky survey, NASA's Tran…

Hyades Member K2-136c: The Smallest Planet in an Open Cluster with a Precisely Measured Mass

Andrew W. Mayo, Courtney D. Dressing, Andrew Vanderburg +39

K2-136 is a late-K dwarf ( M) in the Hyades open cluster with three known, transiting planets and an age of Myr. Analyzing K2 photometry, we found…

TOI-4562 b: A highly eccentric temperate Jupiter analog orbiting a young field star

Alexis Heitzmann, George Zhou, Samuel N. Quinn +47

We report the discovery of TOI-4562 b (TIC-349576261), a Jovian planet orbiting a young F7V-type star, younger than the Praesepe/Hyades clusters (< Myr). This planet stands o…

A Mini-Neptune from TESS and CHEOPS Around the 120 Myr Old AB Dor member HIP 94235

George Zhou, Christopher P. Wirth, Chelsea X. Huang +36

The TESS mission has enabled discoveries of the brightest transiting planet systems around young stars. These systems are the benchmarks for testing theories of planetary evolution…

NEID Rossiter-McLaughlin Measurement of TOI-1268b: A Young Warm Saturn Aligned with Its Cool Host Star

Jiayin Dong, Chelsea X. Huang, George Zhou +56

Close-in gas giants present a surprising range of stellar obliquity, the angle between a planet's orbital axis and its host star's spin axis. It is unclear whether the obliquities…

The NANOGrav 11-year Data Set: Constraints on Planetary Masses Around 45 Millisecond Pulsars

E. A. Behrens, S. M. Ransom, D. R. Madison +27

We search for extrasolar planets around millisecond pulsars using pulsar timing data and seek to determine the minimum detectable planetary masses as a function of orbital period.…

The Liquidus Temperature for Methanol-Water Mixtures at High Pressure and Low Temperature, with Application to Titan

A. J. Dougherty, Z. T. Bartholet, R. J. Chumsky +3

Methanol is a potentially important impurity in subsurface oceans on Titan and Enceladus. We report measurements of the freezing of methanol-water samples at pressures up to 350~MP…

Studying the solar system with the International Pulsar Timing Array

R. N. Caballero, Y. J. Guo, K. J. Lee +77

Pulsar-timing analyses are sensitive to errors in the solar-system ephemerides (SSEs) that timing models utilise to estimate the location of the solar-system barycentre, the quasi-…

Measuring the mass of solar system planets using pulsar timing

D. J. Champion, G. B. Hobbs, R. N. Manchester +19

High-precision pulsar timing relies on a solar-system ephemeris in order to convert times of arrival (TOAs) of pulses measured at an observatory to the solar system barycenter. Any…
