The CHEOPS view of the climate of WASP-3 b
Alonso, R.; Deleuil, M.; Erikson, A. +83 more
Context. Hot Jupiters are giant planets subject to intense stellar radiation. The physical and chemical properties of their atmosphere make them the most amenable targets for atmospheric characterization. Aims. In this paper we analyze the photometry collected during the secondary eclipses of the hot Jupiter WASP-3 b by CHEOPS, TESS, and Spitzer. …
Internal Structure of the Magnetic Funnel in the Polar Heliosphere
Kislov, R. A.
According to data obtained by the Ulysses spacecraft in 2017, high-latitude current sheets have been discovered in the polar heliosphere. They have been observed during solar activity minima in 1994 and 2007 at a distance of 2–3 AU above the south pole of the Sun. The discovered current sheets formed a conical surface rotating as a whole around th…
Interaction between a Coronal Mass Ejection and Comet 67P/Churyumov–Gerasimenko
Gombosi, Tamas I.; Combi, Michael R.; Altwegg, Kathrin +6 more
The interaction between a coronal mass ejection (CME) and a comet has been observed several times by in situ observations from the Rosetta Plasma Consortium, which is designed to investigate the cometary magnetosphere of comet 67P/Churyumov–Gerasimenko (CG). Goetz et al. reported a magnetic field of up to 300 nT measured in the inner coma, which i…
Repeated and Long-Lasting Fault Activation on Amazonian Mars as Demonstrated by Tectonically Induced Landslides
Fawdon, P.; Balme, M. R.; Rothery, D. A. +1 more
We identify and analyze a large shortening structure (surface expression of a thrust fault) in western Arabia Terra, Mars, exhibiting recent, repeated, and long-lasting tectonic activity. Where the fault system deforms Marsabit crater rim, four landslides with differing degradation states extend onto the crater floor. We propose these were trigger…
JCMT 850 µm Continuum Observations of Density Structures in the G35 Molecular Complex
Tsai, Chao-Wei; Sanhueza, Patricio; Tej, Anandmayee +32 more
Filaments are believed to play a key role in high-mass star formation. We present a systematic study of the filaments and their hosting clumps in the G35 molecular complex using James Clerk Maxwell Telescope SCUBA-2 850 µm continuum data. We identified five clouds in the complex and 91 filaments within them, some of which form 10 hub–filamen…
Mapping "Brain Terrain" Regions on Mars Using Deep Learning
Zhao, Daniel; Noe, Eldar; Morgan, Alexander M. +2 more
One of the main objectives of the Mars Exploration Program is to search for evidence of past or current life on the planet. To achieve this, Mars exploration has been focusing on regions that may have liquid or frozen water. A set of critical areas may have seen cycles of ice thawing in the relatively recent past in response to periodic changes in…
Martian paleolake outlet canyons - Evidence for controls on valley network formation
Sefton-Nash, Elliot; Miguel, Yamila; Diamant, Sharon J. M. +1 more
Martian valley networks (VNs) have been viewed as one of the most compelling pieces of evidence for ancient fluvial activity during the Late Noachian and Early Hesperian periods (3.7-3.5 Ga), likely as a result of precipitation (snowfall/rainfall). During this period, paleolakes also formed, predominantly due to water accumulation within impact cr…
Investigation of X-band and Ka-band amplitude scintillation based on measurement data collected during ESA's BepiColombo superior solar conjunction campaign
Chen, Shun-Ping; Lanucara, Marco; Villalvilla, Jose
Solar phase scintillation and solar amplitude scintillation are fundamentally important in deep space mission operations for designing a communication system capable of transmitting signals when the signal path is close to the Sun. The ESA's BepiColombo measurement data were analyzed in a previous paper in terms of the power spectral density of th…
Characterizing High-Energy Solar Proton Events with Energies Below and Above 100 MeV
Vainio, Rami; Valtonen, Eino; Al-Sawad, Amjad +1 more
We analyzed 58 high-energy proton events that occurred during the years 1996 – 2022. In 32 out of the 58 (55%) events, the proton energies extended up to
FAST Observations of Four Comets to Search for the Molecular Line Emissions between 1.0 and 1.5 GHz Frequencies
Tsai, Chao-Wei; Duan, Yan; Li, Di +11 more
We used the Five-hundred-meter Aperture Spherical radio Telescope (FAST) to search for the molecular emissions in the L-band between 1.0 and 1.5 GHz toward four comets, C/2020 F3 (NEOWISE), C/2020 R4 (ATLAS), C/2021 A1 (Leonard), and 67P/Churyumov-Gerasimenko during or after their perihelion passages. Thousands of molecular transition lines fall i…
