A free-floating-planet microlensing event caused by a Saturn-mass object
Subo Dong, Zexuan Wu, Yoon-Hyun Ryu +39
A population of free-floating planets is known from gravitational microlensing surveys. None have a directly measured mass, owing to a degeneracy with the distance, but the populat…
Time-resolved p-mode oscillations for subgiant HD 142091 with NEID at WIYN
Jacob K. Luhn, Paul Robertson, Samuel Halverson +22
Detections of Earth-analog planets in radial velocity observations are limited by stellar astrophysical variability occurring on a variety of timescales. Current state-of-the-art m…
The Impact of Fiber Cross Contamination on Radial Velocity Precision
Chenyang Ji, Sharon Xuesong Wang, Kai Zhang +1
High-resolution spectrographs with precise radial velocity (PRV) capabilities require careful considerations in instrumental design and data processing in order to reach the 10 cm/…
Short-Period Small Planets with High Mutual Inclinations are more Common around Metal-Rich Stars
Xinyan Hua, Sharon Xuesong Wang, Dongsheng An +7
We present a correlation between the stellar metallicities and the mutual inclinations of multi-planet systems hosting short-period small planets (a/Rs<12, Rp<4Re). We analyzed 89…
The Spectrum of C/2023 A3 Indicates A Depleted Composition
Yunyi Tang, Shihao Wang, Zixuan Lin +4
We report a spectroscopic observation of comet C/2023 A3 using an 80 mm apochromatic (apo) refractor equipped with a custom-built spectrometer with a resolution of R~2,500 on the n…
Metallicity Dependence of Giant Planets around M Dwarfs
Tianjun Gan, Christopher A. Theissen, Sharon X. Wang +2
We investigate the stellar metallicity ([Fe/H] and [M/H]) dependence of giant planets around M dwarfs by comparing the metallicity distribution of 746 field M dwarfs without known…
Relative Occurrence Rate Between Hot and Cold Jupiters as an Indicator to Probe Planet Migration
Tianjun Gan, Kangrou Guo, Beibei Liu +4
We propose a second-order statistic parameter , the relative occurrence rate between hot and cold Jupiters (), to probe the migratio…
A Second Planet Transiting LTT 1445A and a Determination of the Masses of Both Worlds
J. G. Winters, R. Cloutier, A. A. Medina +79
LTT 1445 is a hierarchical triple M-dwarf star system located at a distance of 6.86 parsecs. The primary star LTT 1445A (0.257 M_Sun) is known to host the transiting planet LTT 144…
