Twin Worlds, Divergent Fates: How Obliquity has differently shaped Pluto's and Triton's landscapes and climates
Tanguy Bertrand, François Forget, Emmanuel Lellouch
Triton and Pluto are believed to share a common origin, both forming initially in the Kuiper Belt but Triton being later captured by Neptune. Both objects display similar sizes, de…
Impact of the coagulation of dust particles on Mars during the 2018 global dust storm
Tanguy Bertrand, Melinda Kahre, Richard Urata +4
Coagulation of particles occurs when two particles collide and stick together. In the Martian atmosphere, dust coagulation would increase the effective particle size, as small part…
Large-scale cryovolcanic resurfacing on Pluto
Kelsi N. Singer, Oliver L. White, Bernard Schmitt +22
The New Horizons spacecraft returned images and compositional data showing that terrains on Pluto span a variety of ages, ranging from relatively ancient, heavily cratered areas to…
Volatile transport modeling on Triton with new observational constraints
T. Bertrand, E. Lellouch, B. J. Holler +18
Neptune's moon Triton shares many similarities with Pluto, including volatile cycles of N2, CH4 and CO, and represents a benchmark case for the study of surface-atmosphere interact…
The Dark Side of Pluto
Tod R. Lauer, John R. Spencer, Tanguy Bertrand +12
During its departure from Pluto, New Horizons used its LORRI camera to image a portion of Pluto's southern hemisphere that was in a decades-long seasonal winter darkness, but still…
Pluto's atmosphere observations with ALMA: spatially-resolved maps of CO and HCN emission and first detection of HNC
E. Lellouch, B. Butler, R. Moreno +6
Following the detection of CO and HCN in Pluto's atmosphere, we report on new ALMA observations of Pluto with two main goals: (i) obtaining spatially-resolved measurements (~0.06''…
Morphological Comparison of Blocks in Chaos Terrains on Pluto, Europa, and Mars
Helle L. Skjetne, Kelsi N. Singer, Brian M. Hynek +12
Chaos terrains are characterized by disruption of preexisting surfaces into irregularly arranged mountain blocks with a chaotic appearance. Several models for chaos formation have…
Global Climate Model Occultation Lightcurves Tested by August 2018 Ground-Based Stellar Occultation
Sihe Chen, Eliot F. Young, Leslie A. Young +3
Pluto's atmospheric profiles (temperature and pressure) have been studied for decades from stellar occultation lightcurves. In this paper, we look at recent Pluto Global Climate Mo…
Formation, Composition, and History of the Pluto System: A Post-New-Horizons Synthesis
William B. McKinnon, Christopher R. Glein, Tanguy Bertrand +1
The Pluto-Charon system provides a broad variety of constraints on planetary formation, composition, chemistry, and evolution. Pluto was the first body to be discovered in what is…
Pluto's Haze as a Surface Material
W. M. Grundy, T. Bertrand, R. P. Binzel +37
Pluto's atmospheric haze settles out rapidly compared with geological timescales. It needs to be accounted for as a surface material, distinct from Pluto's icy bedrock and from the…
Pluto's lower atmosphere and pressure evolution from ground-based stellar occultations, 1988-2016
E. Meza, B. Sicardy, M. Assafin +167
Context. Pluto's tenuous nitrogen (N2) atmosphere undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has been recently (July 2015) observed by th…
The CH4 cycles on Pluto over seasonal and astronomical timescales
T. Bertrand, F. Forget, O. M. Umurhan +13
New Horizons observations suggest that CH4 on Pluto has a complex history, involving reservoirs of different composition, thickness and stability controlled by volatile processes o…
The nitrogen cycles on Pluto over seasonal and astronomical timescales
T. Bertrand, F. Forget, O. M. Umurhan +13
Pluto's landscape is shaped by the cycles of the volatile ices covering its surface. In particular, the Sputnik Planitia (SP) ice sheet displays a large diversity of terrains, with…
3D modeling of organic haze in Pluto's atmosphere
Tanguy Bertrand, François Forget
The New Horizons spacecraft, which flew by Pluto on July 14, 2015, revealed the presence of haze in Pluto's atmosphere that were formed by CH4/N2 photochemistry at high altitudes i…
