Space scientists reveal secret behind Jupiter's 'energy crisis'
Jupiter's atmospheric heating gas giant Jupiter
2021/8/9
New research has revealed the solution to Jupiter's 'energy crisis', which has puzzled astronomers for decades. Astronomers have created a detailed global map of the gas giant's upper atmosphere, conf...
A cosmic barbecue:Researchers spot 60 new ‘hot Jupiter’ candidates
A cosmic barbecue Researchers 60 new hot Jupiter candidates
2017/7/24
Yale researchers have identified 60 potential new “hot Jupiters” — highly irradiated worlds that glow like coals on a barbecue grill and are found orbiting only 1% of Sun-like stars.Hot Jupiters const...
First results from long-term,hi-res tracking of eruptions on Jupiter's moon Io
long-term hi-res tracking eruptions Jupiter moon Io
2016/11/4
Jupiter’s moon Io continues to be the most volcanically active body in the solar system, as documented by the longest series of frequent, high-resolution observations of the moon’s thermal emission ev...
New radio map of Jupiter reveals what’s beneath colorful clouds
New radio map Jupiter beneath colorful clouds
2016/6/12
tronomers using the upgraded Karl G. Jansky Very Large Array in New Mexico have produced the most detailed radio map yet of the atmosphere of Jupiter, revealing the massive movement of ammonia gas tha...
Temperature-Pressure Profile of the hot Jupiter HD 189733b from HST Sodium Observations: Detection of Upper Atmospheric Heating
spectroscopic planetary systems individual HD 189733b
2012/2/23
We present transmission spectra of the hot Jupiter HD 189733b taken with the Space Telescope Imaging Spectrograph aboard HST. The spectra cover the wavelength range 5808-6380 Ang with a resolving powe...
The hot-Jupiter Kepler-17b: discovery, obliquity from stroboscopic starspots, and atmospheric characterization
hot-Jupiter Kepler-17b discovery stroboscopic starspots atmospheric characterization
2011/10/20
This paper reports the discovery and characterization of the transiting hot giant exoplanet Kepler-17b. The planet has an orbital period of 1.486 days, and radial velocity measurements from the Hobby-...
Two phase, inward-then-outward migration of Jupiter and Saturn in the gaseous Solar Nebula
accretion, accretion disks – planets and satellites: formation – hydrodynamics – methods: numerical
2011/10/20
It has recently been shown that the terrestrial planets and asteroid belt can be reproduced if the giant planets underwent an inward-then-outward migration (the "Grand Tack"; Walsh et al 2011). Inward...
Radio Interferometric Planet Search II: Constraints on sub-Jupiter-Mass Companions to GJ 896A
Interferometric Planet Constraints sub-Jupit
2011/10/10
We present results from the Radio Interferometric Planet (RIPL) search for compan- ions to the nearby star GJ 896A. We present 11 observations over 4.9 years. Fitting astrometric parameters to the dat...
The First Kepler Mission Planet Confirmed With The Hobby-Eberly Telescope: Kepler-15b, a Hot Jupiter Enriched In Heavy Elements
Hot Jupiter Enriched Heavy Elements Planet Confirmed
2011/10/9
We report the discovery of Kepler-15b, a new transiting exoplanet detected by NASA's Kepler mission. The transit signal with a period of 4.94 days was detected in the quarter 1 (Q1) Kepler photometry....
Considerations on the accretion of Uranus and Neptune by mutual collisions of planetary embryos in the vicinity of Jupiter and Saturn
planetary systems – planets and satellites: formation – planets and satellites: individual: Uranus, Neptune – protoplanetary disks
2011/10/8
Modeling the formation of Uranus and Neptune is a long-lasting problem in planetary science. Due to the gas-drag, collisional damping, and resonant shepherding, the planetary embryos repel the planete...
Transiting exoplanets from the CoRoT space mission. XVIII. CoRoT-18b: a massive hot jupiter on a prograde, nearly aligned orbit
stars: planetary systems - techniques: photometry - techniques: radial velocities - techniques: spectroscopic
2011/9/30
We report the detection of CoRoT-18b, a massive hot jupiter transiting in front of its host star with a period of 1.9000693 +/- 0.0000028 days. This planet was discovered thanks to photometric data se...
The upper atmospheres of close-in gas giant exoplanets (“hot Jupiters”) are subjected to intense heating and tidal forces from their parent stars. The atomic (H) and ionized (H+) hydrogen layers are s...
On the Inference of Thermal Inversions in Hot Jupiter Atmospheres
Thermal Inversions Hot Jupiter Atmospheres
2011/1/10
Several studies in the recent past have inferred the existence of thermal inversions in some transiting hot Jupiter atmospheres. Given the limited data available, the inference of a thermal inversion ...
