X-Ray Emission from Jupiter, Saturn, and Earth: A Short Review [PDF]
, 2006 Jupiter, Saturn, and Earth - the three planets having dense atmosphere and a well developed magnetosphere - are known to emit X-rays. Recently, Chandra X-ray Observatory has observed X-rays from these planets, and XMM-Newton has observed them from ...

On the volatile enrichments and composition of Jupiter [PDF]
, 2005 Using the clathrate hydrates trapping theory, we discuss the enrichments in volatiles in the atmosphere of Jupiter measured by the \textit{Galileo} probe in the framework of new extended core-accretion planet formation models including migration and disk

The NIR transmission spectrum of Jupiter from the observation of a Ganymede’s eclipse
EPJ Web of Conferences, 2015 Here, we report the NIR transmission spectrum of Jupiter, with high signal-to-noise ratio, as if it were a transiting planet. Our technique was to observe Ganymede, when crossing Jupiter’s shadow.

New Constraints on the Composition of Jupiter from Galileo Measurements and Interior Models [PDF]
, 1997 Using the helium abundance measured by Galileo in the atmosphere of Jupiter and interior models reproducing the observed external gravitational field, we derive new constraints on the composition and structure of the planet.

The Atmospheric Circulation of Ultra-hot Jupiters [PDF]
The Astrophysical Journal, 2019 Abstract Recent observations of ultra-hot Jupiters with dayside temperatures in excess of 2500 K have found evidence for new physical processes at play in their atmospheres. In this work, we investigate the effects of the dissociation of molecular hydrogen and recombination of atomic hydrogen on the atmospheric circulation of ultra-hot ...

Highly Depleted Alkali Metals in Jupiter’s Deep Atmosphere
The Astrophysical Journal Letters, 2023 Water and ammonia vapors are known to be the major sources of spectral absorption at pressure levels observed by the microwave radiometer (MWR) on Juno. However, the brightness temperatures and limb darkening observed by the MWR at its longest-wavelength

The thermal structure of the atmosphere of Jupiter [PDF]
The Astrophysical Journal, 1974 Radiative equilibrium models of the Jovian atmosphere calculated by Hogan, Rasool, and Encrenaz (1969) and by Cess and Khetan (1973) are shown to be in conflict. A new calculation is presented which agrees closely with that of Cess and Khetan. This model, however, fails to predict the observed intensity in the 7.8-micron methane band by about a factor ...

Research on Jupiter's magnetic field: Review and prospect
地球与行星物理论评The internal structure and dynamics of different planets are different, so some planets have an intrinsic magnetic field, and some have not yet found an intrinsic magnetic field.

Enhancement of deuterated ethane on Jupiter [PDF]
, 2001 We report laboratory measurements of cross sections of CH_3D and C_2H_5D in the extreme ultraviolet. The results are incorporated in a photochemical model for the deuterated hydrocarbons up to C_2 in the upper atmosphere of Jupiter, taking into account ...

JWST Measurements of 13C, 18O, and 17O in the Atmosphere of Super-Jupiter VHS 1256 b
The Astrophysical Journal Letters, 2023 Isotope ratios have recently been measured in the atmospheres of directly imaged and transiting exoplanets from ground-based observations. The arrival of JWST allows us to characterize exoplanetary atmospheres in further detail and opens up wavelengths ...
