The TESS-Keck Survey XVII: Precise Mass Measurements in a Young, High Multiplicity Transiting Planet System using Radial Velocities and Transit Timing Variations
Corey Beard, Paul Robertson, Fei Dai +41
We present a radial velocity (RV) analysis of TOI-1136, a bright TESS system with six confirmed transiting planets, and a seventh single-transiting planet candidate. All planets in…
TOI-1801 b: A temperate mini-Neptune around a young M0.5 dwarf
M. Mallorquín, E. Goffo, E. Pallé +79
We report the discovery, mass, and radius determination of TOI-1801 b, a temperate mini-Neptune around a young M dwarf. TOI-1801 b was observed in TESS sectors 22 and 49, and the a…
Accurate and efficient photo-eccentric transit modeling
Mason G. MacDougall, Gregory J. Gilbert, Erik A. Petigura
A planet's orbital eccentricity is fundamental to understanding the present dynamical state of a system and is a relic of its formation history. There is high scientific value in m…
The TESS-Keck Survey. XVI. Mass Measurements for 12 Planets in Eight Systems
Joseph M. Akana Murphy, Natalie M. Batalha, Nicholas Scarsdale +44
With JWST's successful deployment and unexpectedly high fuel reserves, measuring the masses of sub-Neptunes transiting bright, nearby stars will soon become the bottleneck for char…
A close-in giant planet escapes engulfment by its star
Marc Hon, Daniel Huber, Nicholas Z. Rui +39
When main-sequence stars expand into red giants, they are expected to engulf close-in planets. Until now, the absence of planets with short orbital periods around post-expansion, c…
The TESS-Keck Survey. XV. Precise Properties of 108 TESS Planets and Their Host Stars
Mason G. MacDougall, Erik A. Petigura, Gregory J. Gilbert +38
We present the stellar and planetary properties for 85 TESS Objects of Interest (TOIs) hosting 108 planet candidates which comprise the TESS-Keck Survey (TKS) sample. We combine ph…
Scaling K2. VI. Reduced Small Planet Occurrence in High Galactic Amplitude Stars
Jon K. Zink, Kevin K. Hardegree-Ullman, Jessie L. Christiansen +13
In this study, we performed a homogeneous analysis of the planets around FGK dwarf stars observed by the Kepler and K2 missions, providing spectroscopic parameters for 310 K2 targe…
The Kepler Giant Planet Search. I: A Decade of Kepler Planet-host Radial Velocities from W. M. Keck Observatory
Lauren M. Weiss, Howard Isaacson, Andrew W. Howard +17
Despite the importance of Jupiter and Saturn to Earth's formation and habitability, there has not yet been a comprehensive observational study of how giant exoplanets correlate wit…
An unlikely survivor: a low-density hot Neptune orbiting a red giant star
Samuel Grunblatt, Nicholas Saunders, Daniel Huber +14
Hot Neptunes, gaseous planets smaller than Saturn ( 3-8 R) with orbital periods less than 10 days, are rare. Models predict this is due to high-energy stellar irradi…
