Separating Super-puffs versus Hot Jupiters among Young Puffy Planets

open access: yesThe Astrophysical Journal
Discoveries of close-in young puffy ( R _p ≳ 6 R _⊕ ) planets raise the question of whether they are bona fide hot Jupiters or puffed-up Neptunes, potentially placing constraints on the formation location and timescale of hot Jupiters.

Hot Jupiters around M dwarfs

open access: yesEPJ Web of Conferences, 2013
The WFCAM Transit Survey (WTS) is a near-infrared transit survey running on the United Kingdom Infrared Telescope (UKIRT). We conduct Monte Carlo transit injection and detection simulations for short period (

Magnetohydrodynamical Torsional Oscillations from Thermoresistive Instability in Hot Jupiters

open access: yesThe Astrophysical Journal, 2023
Hot Jupiter atmospheres may be subject to a thermoresistive instability where an increase in the electrical conductivity due to ohmic heating results in runaway of the atmospheric temperature.

Evidence for Primordial Alignment II: Insights from Stellar Obliquity Measurements for Hot Jupiters in Compact Multiplanet Systems

open access: yesThe Astronomical Journal
A significant fraction of hot Jupiters have orbital axes misaligned with their host stars’ spin axes. The large stellar obliquities of these giants have long been considered potential signatures of high-eccentricity migration, which is expected to clear ...

Atmospheric Circulation of Hot Jupiters: Dayside–Nightside Temperature Differences. II. Comparison with Observations [PDF]

open access: yes, 2016
The full-phase infrared light curves of low-eccentricity hot Jupiters show a trend of increasing fractional dayside–nightside brightness temperature difference with increasing incident stellar flux, both averaged across the infrared and in each ...

THE IMPRINT OF EXOPLANET FORMATION HISTORY ON OBSERVABLE PRESENT-DAY SPECTRA OF HOT JUPITERS [PDF]

open access: yes, 2016
The composition of a planet’s atmosphere is determined by its formation, evolution, and present-day insolation. A planet’s spectrum therefore may hold clues on its origins.

Flexible Polyurethane Foams Reinforced With Recycled Waste Tire Material

open access: yesPolymer Engineering &Science, Volume 65, Issue 10, Page 5491-5506, October 2025.
Ground tire rubber powder obtained through water jet pulverization mixed with PU foam possesses tunable mechanical and acoustic properties suitable for automotive, construction, and aerospace applications. ABSTRACT We explore the use of ground tire rubber (GTR) powder obtained through water jet pulverization (WJP), referred to as WJP‐GTR, and reveal ...

Spin and Obliquity Evolution of Hot Jupiter Hosts from Resonance Locks

open access: yesThe Astrophysical Journal
When a hot Jupiter orbits a star whose effective temperature exceeds ∼6100 K, its orbit normal tends to be misaligned with the stellar spin axis. Cooler stars typically have smaller obliquities, which may have been damped by hot Jupiters in resonance ...

Structure and Evolution of Internally Heated Hot Jupiters

open access: yes, 2017
Hot Jupiters receive strong stellar irradiation, producing equilibrium temperatures of $1000 - 2500 \ \mathrm{Kelvin}$. Incoming irradiation directly heats just their thin outer layer, down to pressures of $\sim 0.1 \ \mathrm{bars}$.
