A living catalog of stream interaction regions in the Parker Solar Probe era
R. C. Allen, G. C. Ho, L. K. Jian +15
Stream interaction regions (SIRs) and corotating interaction regions (CIRs) are important phenomena in heliospheric physics. These large-scale structures vary temporally and spatia…
Discovery of a second-generation planet candidate accreting onto a white dwarf
Jamie T. Williams, Boris T. Gänsicke, Nicholas C. Stone +10
Many white dwarfs accrete the debris of disrupted planetary bodies, detected in the form of metal-enrichment in their atmospheres, dusty or gaseous circumstellar discs, and photome…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Simultaneous Mars-orbit observations reveal Kelvin-Helmholtz instability-driven bulk atmospheric ion escape
Chi Zhang, Chuanfei Dong, Gangkai Poh +11
Atmospheric ion escape driven by the solar wind is a key process controlling the long-term loss of the Martian atmosphere. Localized plasma clouds can carry substantial fluxes of p…
Direct detections of white dwarfs in four WD+dM post-common envelope binaries within 20 pc
Mairi W. O'Brien, David J. Wilson, Pier-Emmanuel Tremblay +5
Characterising post-common envelope binaries (PCEBs) containing a white dwarf and a main-sequence companion is essential for improving theories of binary evolution. This paper pres…
SADCat: A Catalog of Supra-Arcade Downflow Events in Solar Flares
Trestan F. Simon, Ryan J. French
Supra-arcade downflows (SADs) are sunward-traveling features routinely observed in hot fan structures above magnetic loop arcades during eruptive solar flares. We manually compiled…
Comparing Monte Carlo Models of Impact Alteration of Planetary Atmospheres
MIkayla R. Huffman, David A. Brain, Kelsi N. Singer +2
One process that affects atmospheric surface pressure is impact bombardment. The evolution of a planet's atmosphere under impact bombardment is an open question. We use a Monte Car…
Stellar Forcing of (exo)Planetary Environments
Julián D. Alvarado-Gómez, Erika Palmerio, Manuel Güdel +13
The environments of exoplanets are fundamentally shaped by the magnetic activity of their host stars through radiative, plasma, and particle-driven processes. This article presents…
Upper Limits on Planet-Induced GHz Radio Emission from Inactive M Dwarfs
Jackie Villadsen, Carter Russell, Luna Guerrero +9
Nearby short-period exoplanet systems may produce detectable stellar radio emission due to sub-Alfvénic star-planet interaction (SPI), but there are no confirmed cases yet. We targ…
Maximum Lifetime of the Vegetative Biosphere
Jacob Haqq-Misra, Eric Wolf
We use a three-dimensional model to calculate steady-state climates at various intervals in Earth's future, across a parameter space of increasing insolation and decreasing CO…
Investigating Pre-flare Signatures in Spectroscopic Observations of an X9-class Solar Flare
Louis Seyfritz, Maria Kazachenko, Ryan French
On October 3rd, 2024, the Sun emitted an X9.0-class flare from active region NOAA 13842. The event was recorded by multiple space-based instruments, beginning hours before the erup…
Stellar flare-driven evolution of primordial early exo-Earth atmospheres: Insights from a Young M Dwarf Flare model
E. Mamonova, K. Herbst, V. Kofman +4
Context. M dwarfs are key targets for terrestrial exoplanet studies, with prospects for atmospheric spectroscopy. However, strong stellar magnetic activity and frequent flaring req…
Thermal Segregation and Reddening in Europa's Double Ridges
Kya C. Sorli, Paul O. Hayne, Lucas Lange +1
Europa's double ridges often display lower albedo and redder color than their surroundings. Their unique topography may cause sublimation-driven darkening due to illumination and s…
Simultaneous TRACERS and THEMIS Observations of Reversed Cusp Ion Dispersions and Dual-Lobe Reconnection
M. Øieroset, S. A. Fuselier, J. B. Bonnell +20
We present observations from two consecutive TRACERS-2 orbits through the northern low-altitude cusp. During the first crossing, TRACERS-2 observed reversed cusp ion dispersion and…
Disentangling auroral, cloud and magnetic spot driven variability in three early L-dwarfs with HST/WFC3
C. O'Toole, J. M. Vos, E. N. Nasedkin +5
Variability monitoring provides an unparalleled insight into the atmospheric processes of brown dwarfs and directly imaged exo-planets. Inhomogeneous clouds, aurorae and magnetic s…
Anti-Solar Differential Rotation May Have Revived Magnetic Braking in the Subgiant 31 Aquilae
Travis S. Metcalfe, Jennifer L. van Saders, Thomas R. Ayres +16
Recent observations have shown that sufficiently slow rotation disrupts the organization of large-scale magnetic field in older main-sequence stars, leading to weakened magnetic br…
Empirical flare energy limits for the largest historical sunspots
N. A. Krivova, T. Chatzistergos, M. Kazachenko +1
Extreme solar particle events reveal that the Sun can occasionally produce eruptions significantly more energetic than those observed in the modern era. These events are thought to…
The Effect of Planetary Rotation Period on Clouds in a Global Climate Model with a Bin Microphysics Scheme
Huanzhou Yang, Eric T. Wolf, Cheng-Cheng Liu +3
Clouds are the largest source of uncertainty in climate simulations. For exoplanets, cloud simulation is particularly challenging because of the lack of observational data to tune…
X-ray and Hα superflare on an RS CVn-type star, UX Arietis: Constraint on the flare location from radial velocity change during the flare
Sota Urabe, Yohko Tsuboi, Kosuke Namekata +5
We report on a giant stellar flare from the RS CVn-type binary UX Arietis, detected with the Monitor of All-sky X-ray Image (MAXI) and followed by a 12-day optical spectroscopic ca…
