Temporal Evolution of the High-energy Irradiation and Water Content of TRAPPIST-1 Exoplanets by Bourrier, V., Bolmont, E., Stamenković, V., Wheatley, P. J., Burgasser, A. J, Delrez, L., Demory, B.-O., Ehrenreich, D., Gillon, M., Jehin, E., Leconte, J., Lederer, S. M., Lewis, N., Triaud, A. H. M. J., Grootel, V. Van, de Wit, Julien

“…Based on the current knowledge of the stellar irradiation, we investigated the likely history of water loss in the system. Planets b to d might still be in a runaway phase, and planets within the orbit of TRAPPIST-1g could have lost more than 20 Earth oceans after 8 Gyr of hydrodynamic escape. …”

Tracing pre-eruptive magma degassing using (Pb-210/Ra-226) disequilibria in the volcanic deposits of the 1980-1986 eruption of Mount St. Helens by Berlo, K, Turner, S, Blundy, J, Black, S, Hawkesworth, C

“…The time scale of diffuse, non-eruptive gas escape prior to 1980 as documented by 210Pb deficits is on the order of a decade using the model developed by Gauthier and Condomines (Earth Planet. …”

TOI-1759 b: A transiting sub-Neptune around a low mass star characterized with SPIRou and TESS by Seager, Sara

“…At 0.1176 ± 0.0013 au from the star, the planet receives 6.4 times the bolometric flux incident on Earth, and its equilibrium temperature is estimated at 433 ± 14 K. …”

Pitted-Ground Volcanoes on Mercury by Ru Xu, Zhiyong Xiao, Yichen Wang, Rui Xu

“…Pitted-ground volcanoes that are developed in lava flows with the same age have different preservation states, suggesting that the pits were not formed by escape of thermally destabilized volatiles from substrate and subsequent roof collapses. …”

Formation of CO2 Driven by Photochemistry of Water Ice Mixed with Carbon Grains by Alexey Potapov, Dmitry Semenov, Cornelia Jäger, Thomas Henning

“…We present results on photochemistry of carbon-grains/water-ice mixtures at temperatures from 10 to 150 K. Such a temperature range corresponds to the physical conditions found in molecular clouds, hot cores and corinos, protostellar envelopes, and planet-forming and debris disks. …”
