Exoplanet statistics and theoretical implications

W Zhu, S Dong - Annual Review of Astronomy and Astrophysics, 2021 - annualreviews.org
In the past few years, significant advances have been made in understanding the
distributions of exoplanet populations and the architecture of planetary systems. We review …

The orbital eccentricity of small planet systems

V Van Eylen, S Albrecht, X Huang… - The Astronomical …, 2019 - iopscience.iop.org
We determine the orbital eccentricities of individual small Kepler planets, through a
combination of asteroseismology and transit light-curve analysis. We are able to constrain …

About 30% of Sun-like stars have Kepler-like planetary systems: a study of their intrinsic architecture

W Zhu, C Petrovich, Y Wu, S Dong… - The Astrophysical …, 2018 - iopscience.iop.org
We constrain the intrinsic architecture of Kepler planetary systems by modeling the observed
multiplicities of the transiting planets (tranets) and their transit timing variations (TTVs). We …

An excess of Jupiter analogs in super-earth systems

ML Bryan, HA Knutson, EJ Lee, BJ Fulton… - The Astronomical …, 2019 - iopscience.iop.org
We use radial velocity (RV) observations to search for long-period gas giant companions in
systems hosting inner super-Earth (1–4 R⊕, 1–10 M⊕) planets to constrain formation and …

The super Earth–cold Jupiter relations

W Zhu, Y Wu - The Astronomical Journal, 2018 - iopscience.iop.org
We report relations between inner (< 1 au) super Earths (planets with mass/radius between
Earth and Neptune) and outer (> 1 au) giant planets (mass> 0.3 MJ, or cold Jupiters) around …

TESS's first planet-A super-Earth transiting the naked-eye star π Mensae

D Gandolfi, O Barragán, JH Livingston… - Astronomy & …, 2018 - aanda.org
We report on the confirmation and mass determination of π Men c, the first transiting planet
discovered by NASA's TESS space mission. π Men is a naked-eye (V= 5.65 mag), quiet G0 …

Evidence for a high mutual inclination between the cold Jupiter and transiting super Earth orbiting π Men

JW Xuan, MC Wyatt - Monthly Notices of the Royal Astronomical …, 2020 - academic.oup.com
ABSTRACT π Men hosts a transiting super Earth (P≈ 6.27 d, m≈ 4.82 M⊕, R≈ 2.04 R⊕)
discovered by TESS and a cold Jupiter (P≈ 2093 d, m sin I≈ 10.02 M Jup, e≈ 0.64) …

Giants are bullies: How their growth influences systems of inner sub-Neptunes and super-Earths

B Bitsch, A Izidoro - Astronomy & Astrophysics, 2023 - aanda.org
Observational evidence points to an unexpected correlation between outer giant planets
and inner sub-Neptunes, which has remained unexplained by simulations so far. We utilize …

The California-Kepler survey. VIII. Eccentricities of Kepler planets and tentative evidence of a high-metallicity preference for small eccentric planets

SM Mills, AW Howard, EA Petigura… - The Astronomical …, 2019 - iopscience.iop.org
Characterizing the dependence of the orbital architectures and formation environments on
the eccentricity distribution of planets is vital for understanding planet formation. In this work …
