Bernhard-1: An Eccentric Binary Periodically Obscured by its Misaligned Circumbinary Disk
Zhecheng Hu, Wei Zhu, Ping Chen +2
Bernhard-1 is a proposed KH 15D-like circumbinary disk occultation (CBO) system, but its binary nature and disk geometry have not previously been confirmed. We present new optical…
Spin-Orbit Geometry of AU Mic b and c from Back-to-Back Transits Observed Contemporaneously with Magellan PFS, LCOGT, and CHEOPS
Zitao Lin, Gyula M. Szabó, Krzysztof Sz. Zieliński +37
Young planets offer a unique window into the early stages of planetary evolution. AU Mic is one of the nearest (9.8 pc) pre-main sequence stars (~20 Myr), hosting two transiting Ne…
Photochemical CS Gas Detected on a 20-Myr-old Exoplanet
Fei Dai, Erik Petigura, John Livingston +6
Probing the atmospheres of young exoplanets offers a powerful window into how planetary systems evolve and the physical and chemical processes that drive those early evolutions. We…
An Adolescent and Near-Resonant Planetary System Near the End of Photoevaporation
Mu-Tian Wang, Fei Dai, Hui-Gen Liu +28
Young exoplanets provide vital insights into the early dynamical and atmospheric evolution of planetary systems. Many multi-planet systems younger than 100 Myr exhibit mean-motion…
Six New Circumbinary Disk Occultation (CBO) Candidates from the Zwicky Transient Facility
Zhecheng Hu, Wei Zhu, Shuming Wang +1
Circumbinary disk occultation (CBO) systems, in which a misaligned circumbinary disk periodically obscures the central binary, provide unique probes of disk structure and dynamics.…
Unexpected Near-Resonant and Metastable States of Young Multi-Planet Systems
Zhecheng Hu, Fei Dai, Wei Zhu +4
Recent observations suggest that the incidence of near-resonant planets declines as planetary systems age, making young planetary systems key signposts of early dynamical evolution…
Microlensing events indicate that super-Earth exoplanets are common in Jupiter-like orbits
Weicheng Zang, Youn Kil Jung, Jennifer C. Yee +65
Exoplanets classified as super-Earths are commonly observed on short period orbits, close to their host stars, but their abundance on wider orbits is poorly constrained. Gravitatio…
Detecting Planetary Oblateness in the Era of JWST: A Case Study of Kepler-167e
Quanyi Liu, Wei Zhu, Yifan Zhou +5
Planets may be rotationally flattened, and their oblateness thus provide useful information on their formation and evolution. Here we develop a new algorithm that can compute the t…
OGLE-2015-BLG-0845L: A low-mass M dwarf from the microlensing parallax and xallarap effects
Zhecheng Hu, Wei Zhu, Andrew Gould +51
We present the analysis of the microlensing event OGLE-2015-BLG-0845, which was affected by both the microlensing parallax and xallarap effects. The former was detected via the sim…
Systematic Reanalysis of KMTNet microlensing events, Paper I: Updates of the Photometry Pipeline and a New Planet Candidate
Hongjing Yang, Jennifer C. Yee, Kyu-Ha Hwang +52
In this work, we update and develop algorithms for KMTNet tender-love care (TLC) photometry in order to create an new, mostly automated, TLC pipeline. We then start a project to sy…
ET White Paper: To Find the First Earth 2.0
Jian Ge, Hui Zhang, Weicheng Zang +163
We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time,…
