The signature of wind patterns caused by the interplay rotation and energy redistribution in hot Jupiters is detectable at high spectral resolution, yet no direct comparison has been attempted between predictions from general circulation models (GCMs) observed high-resolution spectra. We present first such comparisons on near-infrared transmission spectra Jupiter HD 189733b. Exploring twelve rates two chemical regimes, we have created model 3-D GCMs cross-correlated them with Comparing our...
We report the discovery of a Neptune-like planet (LP 714-47 b, P = 4.05204 d, m b 30.8 ± 1.5 M ⊕ , R 4.7 0.3 ) located in “hot Neptune desert”.

Abstract The Transiting Exoplanet Survey Satellite mission was designed to find transiting planets around bright, nearby stars. Here, we present the detection and mass measurement of a small, short-period (≈4 days) planet bright ( V = 7.9), solar-type star HD 86226 (TOI-652, TIC 22221375), previously known host long-period (∼1600 giant planet. 86226c (TOI-652.01) has radius 2.16 ± 0.08 R ⊕ <?CDATA ${7.25}_{-1.12}^{+1.19}$?> M , based on archival new radial velocity data.

The abundance of short-period planetary systems with high orbital obliquities relative to the spin their host stars is often taken as evidence that scattering processes play important roles in formation and evolution these systems. More recent studies have suggested wide binary companions can tilt protoplanetary disks, inducing a stellar obliquity form through smooth like disk migration.

ABSTRACT HD 21749 is a bright (V = 8.1 mag) K dwarf at 16 pc known to host an inner terrestrial planet 21749c as well outer sub-Neptune 21749b, both delivered by Transiting Exoplanet Survey Satellite (TESS). Follow-up spectroscopic observations measured the mass of 21749b be 22.7 ± 2.2 M⊕ with density $7.0^{+1.6}_{-1.3}$ g cm−3, making it one densest sub-Neptunes. However, measurement was suspected influenced stellar rotation. Here, we present new high-cadence PFS RV data disentangle...

Abstract Kepler revealed that roughly one-third of Sunlike stars host planets orbiting within 100 days and between the size Earth Neptune. How do these form, what are they made of, represent a continuous population or multiple populations? To help address questions, we began Magellan-TESS Survey (MTS), which uses Magellan II/PFS to obtain radial velocity (RV) masses 30 TESS-detected exoplanets develops an analysis framework connects observed planet distributions underlying populations.

Abstract Thermochemical modeling and shock-tube experiments show that shocks applied to N 2 /CH 4 gas mixtures can synthesize organic molecules. Sufficiently large, hypersonic meteoroids entering the atmosphere of Saturn’s moon Titan should therefore drive chemistry. To do so must be sufficiently large compared atmospheric mean free path at a given altitude generate shocks, deposit enough energy per length produce temperatures high excite dissociate relevant The Cassini spacecraft imaged...

The Cassini-Huygens mission measured the chemical abundances of major components Titan's atmosphere, and analyses data revealed several as-yet unexplained anomalies in methane hydrogen profiles. We model deceleration ablation meteors atmosphere to examine whether meteor energy deposition could explain, part, two these anomalies. Our simulations vary entry mass, trajectory angle, velocity, follow changes all three as our descend into a realistic Titan atmosphere. For smallest particles, which...
