Diffusion map around the small moon Aegaeon (Saturn LIII). Diffusion map around the small moon Aegaeon (Saturn LIII).
Diffusion is computed after a frequency analysis of thousands of test particles. Bluer colors are for stable orbits, redder colors indicate unstable ones. ...(more)
TNO surface colors in g, r, and z bands TNO surface colors in g, r, and z bands
g-r and r-z photometry of TNOs, showing the 3 unique surface types revealed by these three bands. ...(more)

Weather on a Hot Jupiter Weather on a Hot Jupiter
Weather map of the transiting hot Jupiter HD 189733b, illustrated by air pressure (color) and wind velocity fields (arrows), as viewed by someone who descends through the planetary atmosphere. The ...(more)
A super Earth in the habitable zone_animation gif A super Earth in the habitable zone_animation gif
Orbit diagram of the planetary system surrounding the K-dwarf star HD 40307. The grey area indicates the star's habitable zone. Notice that the outermost planet is right in the habitable ...(more)
A back-scattered image of the E44 CAI from the CV3 Efremovka chondrite taken on a scanning electron microscope A back-scattered image of the E44 CAI from the CV3 Efremovka chondrite taken on a scanning electron microscope
A back-scattered image of the E44 CAI from the CV3 Efremovka chondrite taken on a scanning electron microscope. This CAI is of particular interest because of the first demonstration of ...(more)
A new initial abundance of 41Ca in the early solar system A new initial abundance of 41Ca in the early solar system
This isochron diagram shows the inferred 41Ca/40Ca ratio in the E44 CAI from the Efremovka meteorite. 20 years ago, the former existence of 41Ca (half-life = 0.1 Myr) was first ...(more)
The distribution of 26Al/27Al in spinel-hibonite spherules extracted from CM chondrites The distribution of 26Al/27Al in spinel-hibonite spherules extracted from CM chondrites
Inferred 26Al/27Al ratios for spinel-hibonite spherules from Murchison and Paris and the probability density plot derived from the data. The overall 26Al/27Al range in the two groups of SHIBs is ...(more)
Hot Jupiters on Prograde/Retrograde Orbits Hot Jupiters on Prograde/Retrograde Orbits
Schematic of the theoretical model showing the dipole fields of a proto-star that are misaligned with both the stellar spin axis and the orbital plane of a hot Jupiter. Consequently, ...(more)
Planet traps and the population of exoplanetary systems Planet traps and the population of exoplanetary systems
Evolutionary tracks of planet forming at multiple planet traps at which rapid type I planetary migration is halted. Three types of traps are considered: dead zone (red lines), ice line ...(more)
Asymmetric distribution of dust in an eccentric protoplanetary disk Asymmetric distribution of dust in an eccentric protoplanetary disk
Gas (left panel) and dust (right panel) density maps of a face-on protoplanetary disk harboring a gas giant planet of 5 Jupiter masses. ...(more)
Yields of 7Be, 10Be, 26Al, 36Cl, 41Ca, and 53Mn for a chondritic chemistry and the spectral parameters p = 4 and 3He/1H = 0.3 Yields of 7Be, 10Be, 26Al, 36Cl, 41Ca, and 53Mn for a chondritic chemistry and the spectral parameters p = 4 and 3He/1H = 0.3
Yields of 7Be, 10Be, 26Al, 36Cl, 41Ca, and 53Mn for a chondritic chemistry and the spectral parameters p = 4 and 3He/1H = 0.3. The yields are normalized to the ...(more)
Tidal and Magnetic Interactions Between a Hot Jupiter and its Host Star in the Magnetospheric Cavity of a Protoplanetary Disk Tidal and Magnetic Interactions Between a Hot Jupiter and its Host Star in the Magnetospheric Cavity of a Protoplanetary Disk
The upper plot illustrates our model, which shows a hot Jupiter orbiting a CTTS in a magnetospheric cavity of a protoplanetary disk. The initial orbit of the planet is set ...(more)
SMA observations of the Comet C/2002 T7 (LINEAR) SMA observations of the Comet C/2002 T7 (LINEAR)
Top left: SMA image of the 234-GHz continuum emission of Comet C/2002 T7 (LINEAR). The 1.3-mm continuum traces the dust distribution in the inner coma. The blue ellipse shown at ...(more)
