Planets Around Solar Twins/Analogs (PASTA) III: Chemical Clock Relations in Planet-Hosting Solar Analogs
Qinghui Sun, Serat M. Saad, Yuan-Sen Ting +10
Context. Abundance ratios between elements synthesized on different nucleosynthetic timescales provide empirical chemical clocks for estimating stellar ages, but robust calibration…
Measurement-Only Dynamical Phase Transitions in Spin-1 Chains
Kemal Aziz, Haining Pan, J. H. Pixley
We study measurement-only dynamics in an interacting spin-1 chain, using forced, normalized local projections rather than Born-rule-sampled measurement outcomes. Starting from the…
Silver Rate Is (Almost) Optimal for Gradient Descent: The Strongly Convex Case
Kaizhao Liu, Yuhan Ye
We study gradient descent with predetermined nonnegative stepsizes on smooth strongly convex functions. Let and be the condition number. We…
An Evolving Cosmic Shoreline and Sandbar Bounding the Rocky Airless Valley
Barron K. Nguyen, Laura K. Schaefer, Xuan Ji +7
Recent JWST observations challenge the traditional 'cosmic shoreline' from both sides, revealing thick volatile atmospheres on the hottest close-in 'lava worlds,' where irradiation…
Substructure evolution from protoplanetary to debris disks driven by mutually gravitating planetesimals and implications on Kepler resonances and free-floating planets
Yinuo Han, Konstantin Batygin, Fei Dai
Motivated by recent observations suggesting rings found in debris disks are wider than those in protoplanetary disks, we consider a picture in which planetesimals formed in radiall…
A Physically Driven Parameterisation of Multidimensional Atmospheres: Application to the JWST Phase Curve of WASP-121b
Yuanheng Yang, Guo Chen, Xianyu Tan +6
Understanding the multidimensional structure of strongly irradiated exoplanets is essential for interpreting their atmospheric dynamics, chemistry and energy transport, yet current…
Hydrogen airglow from an escaping ultrahot Jupiter atmosphere
Yapeng Zhang, Chenliang Huang, Aaron Householder +17
Intense high-energy irradiation of close-in gaseous exoplanets drives the rapid escape of their atmospheres, fundamentally shaping planetary demographics. While atmospheric loss is…
Super-earths and mini-neptunes follow different orbital period-eccentricity relations
Ke-Ting Shin, Dong-Sheng An, Ji-Wei Xie +2
Many exoplanets have been observed with radius sizes between that of Earth and that of Neptune and are thus classified into two groups: super-earths (SEs) and mini-neptunes (MNs).…
Revisiting the Exo-Mercury Candidate GJ 367 b with ESPRESSO and a Self-Consistent Tidal Distortion Model
Rena A. Lee, Fei Dai, Ellen M. Price +18
We report revised mass and radius measurements for GJ 367 b, an ultra-short-period (7.7 hr) sub-Earth in a multi-planet system orbiting a nearby (~9 pc) M dwarf host. Previous mass…
Modeling the Dynamics and Thermochemistry for the Outer Atmospheres of the Ultra-hot Jupiter WASP-121b
Lile Wang, Yiren Lin, Ji Wang +1
We present three-dimensional simulations of the ultra-hot Jupiter (UHJ) WASP-121b from the planetary surface to extended outflows, coupling hydrodynamics with consistent non-equili…
The Effect of Tidal Heating and Volatile Budgets on the Outgassed Atmosphere of 55 Cancri e
Barron K. Nguyen, Laura K. Schaefer, Fei Dai +1
55 Cancri e is a 8 Gyr rocky world (1.95 , 8.8 ) orbiting a K-type star. JWST observations suggest a carbon-dominated atmosphere (CO/CO) over a global…
Extreme winds on the emerging dayside of an ultrahot Jupiter
Yapeng Zhang, Joost P. Wardenier, Aaron Householder +16
High-resolution spectroscopy provides a unique opportunity to directly probe atmospheric dynamics by resolving Doppler shifts of planetary signal as a function of orbital phases. U…
