Spectroscopic monitoring detects phase-locked flares to Proxima d and flare-intensity modulation by Proxima b, producing a -16 G polar field estimate for the inner planet via Poynting-flux modeling.
Exposure-integrated Gaussian processes allow prediction of both latent stellar signals and instrument-specific binned versions, supporting combination of overlapping EPRV datasets with varying exposure times.
dopplerkernel parametrizes UHJ projected winds with four parameters (v_jet, sigma_jet, v_wind, phi_sink) and retrieves jet and day-to-night flows from synthetic WASP-76b K-band emission spectra generated by three GCMs.
Panchromatic JWST spectrum of WASP-121 b detects SiO and measures refractory-to-volatile ratios 3x stellar, consistent with mixed solid-gas accretion or migration with continued solid accretion.
An empirical Teff-log g-[Fe/H]-[C/Fe] calibration aligns 1D/LTE NIR OH oxygen abundances to the [OI] scale for 35 V/EMP stars, reducing scatter and temperature dependence in [O/Fe] vs [Fe/H].
Solar image analysis shows typical astrometric jitter of 0.342 μas pc from activity, below the ~3 μas Earth-planet signal at 1 pc, so stellar contamination does not prevent Earth-like exoplanet astrometry around Sun-like stars.
Generates and publicly releases 81,498 detrended Kepler light curves plus a catalog of 87 periodic variables (26 new) in the 2.5 Gyr cluster NGC 6819 using Gaia DR3 for membership.
Three Jupiter-mass planets are detected around two low-luminosity red giants with 15–18 yr CORALIE RVs; a multi-exposure strategy averages pulsations below 5 m/s.
MOSES is a vacuum-stabilized white-pupil echelle spectrograph designed for >80,000 resolution over 380-680 nm and sub-2 m/s RV precision via dual-fiber simultaneous Fabry-Pérot calibration on the MONET telescope.
GEODES characterizes three accelerating nearby stars, finding a stellar companion, a 45-Jupiter-mass brown dwarf at about 18 AU, and a 9.5-Jupiter-mass companion that is more likely a planet than a brown dwarf.
Introduces a reflection spectroscopy metric and uses KELT-9 injection-recovery tests to demonstrate that rotational line broadening from rapid stellar rotation and large misalignments must be included when assessing detectability of exoplanet reflected spectra.
TOI-4311 hosts a 0.99-day super-Earth (1.38 R_earth, 4.5 M_earth) and 15-day sub-Neptune (2.47 R_earth), plus a candidate 38-day planet, with the dense inner planet potentially challenging formation theories given the host's galactic population.
TOI-1710 b has a true obliquity of 149 degrees indicating retrograde motion, favoring high-eccentricity migration via planet-planet scattering and Kozai-Lidov cycles for this tidally detached super-Neptune.
NGTS-39 b is a 1.467 MJ, 1.088 RJ transiting warm Jupiter on a 58.2-day eccentric orbit around an F9 dwarf, identified via TESS, NGTS, CORALIE and HARPS data.
Interpolation algorithm choice in template-based RV extraction from high-resolution spectra introduces systematic biases reaching 20-25 m/s in low-SNR cases and under 0.2 m/s when BERV variation is large, demonstrated via Gaussian synthetic spectra and ESPRESSO observations.
Revised mass of 0.503 M_Earth and radius of 0.736 R_Earth for GJ 367 b give a density of 6.9 g cm^{-3} and an iron fraction of 50-70% via new tidal and composition modeling.
TOI-7154b is a 71.7 M_J brown dwarf in an 8.86-day eccentric orbit around a G star, with eccentricity and age suggesting stellar-like fragmentation origins.
Joint radial-velocity analysis revises GJ 3378b's period to 21.45 days and minimum mass to 2.3 Earth masses, placing the habitable-zone planet near the cosmic shoreline.
Refined ephemeris for WASP-18 b with no support found for proposed companion WASP-18 c from combined transit timing and RV analysis.
Mars provides a real-world case study of processes like volatile loss, climate evolution, and magnetism that determine habitability on small rocky planets at the edge of habitable conditions.
