The Planetary Science JournalWith recent advances in exoplanet observational techniques enabling the discovery of increasingly smaller planets, a crucial question emerges in the search for habitable planets: how small can a planet be and still maintain an atmosphere?

A High-precision, Differentiable Code for Solar System Ephemerides
The Planetary Science JournalWe present jorbit , a python/ JAX library designed to enable modern data-driven numerical studies of the solar system. Written entirely in JAX , an autodifferentiable and optionally GPU accelerated language behind many current large-scale machine ...

BIOLOGY: WHAT ONE NEEDS TO KNOW
Zygon, 1996 . Biology on this planet represents an astonishing experiment in carbon‐based chemistry which, over billions of years, has generated billions of species adapted to countless major and minor fluctuations in ecological circumstances. In one sense there is

Metal-polluted White Dwarfs with 21 μm IR Excesses from JWST/MIRI: Planets or Dust?
The Astronomical JournalWhite dwarfs with metal pollution are caused by the accretion of rocky dust from tidally disrupted minor bodies and are signposts for planetary systems. These minor bodies are perturbed by planets that have survived post-main-sequence evolution.

Quantifying the Contamination of TESS Ecliptic-plane Light Curves by Minor Planets
The Astronomical JournalThough missions devoted to time series photometry focus primarily on targets far beyond the solar system, their observations can be contaminated by foreground minor planets, especially near the ecliptic plane, where solar system objects are most ...

Apache Point Rapid Response Characterization of Primitive Imminent Impactor 2024 RW1
The Astronomical JournalImminent impactors may be detected only a few hours before their impact with Earth, providing a brief opportunity to characterize them before impact. We describe the characterization of imminent impactor 2024 RW _1 , which was discovered by the Catalina ...

From planetesimals to planets with N-body simulations in the giant-planet formation region
Astronomy & AstrophysicsThe cores of wide-orbit giant planets can form via pebble accretion if large planetesimals form in the outer regions of protoplanetary discs at sufficiently early times.
