Sun-like stars produce superflares roughly once per century
Valeriy Vasilyev, Timo Reinhold, Alexander I. Shapiro +7
Stellar superflares are energetic outbursts of electromagnetic radiation, similar to solar flares but releasing more energy, up to erg on main sequence stars. It is unkno…
Two Distinct Populations of Dark Comets Delineated by Orbits and Sizes
Darryl Z. Seligman, Davide Farnocchia, Marco Micheli +7
Small bodies are capable of delivering essential prerequisites for the development of life, such as volatiles and organics, to the terrestrial planets. For example, empirical evide…
Pointing Accuracy Improvements for the South Pole Telescope with Machine Learning
P. M. Chichura, A. Rahlin, A. J. Anderson +93
We present improvements to the pointing accuracy of the South Pole Telescope (SPT) using machine learning. The ability of the SPT to point accurately at the sky is limited by its s…
Suppression of the collisionless tearing mode by flow shear: implications for reconnection onset in the Alfvénic solar wind
A. Mallet, S. Eriksson, M. Swisdak +1
We analyse the collisionless tearing mode instability of a current sheet with a strong shear flow across the layer. The growth rate decreases with increasing shear flow, and is com…
A giant planet transiting a 3-Myr protostar with a misaligned disk
Madyson G. Barber, Andrew W. Mann, Andrew Vanderburg +35
Astronomers have found more than a dozen planets transiting 10-40 million year old stars, but even younger transiting planets have remained elusive. A possible reason for the lack…
Rising Near-Ultraviolet Spectra in Stellar Megaflares
Adam F. Kowalski, Rachel A. Osten, Yuta Notsu +5
Flares from M-dwarf stars can attain energies up to times larger than solar flares but are generally thought to result from similar processes of magnetic energy release and…
MAUVE: An Ultraviolet Astrophysics Probe Mission Concept
Mayura Balakrishnan, Rory Bowens, Fernando Cruz Aguirre +18
We present the mission concept "Mission to Analyze the UltraViolet universE" (MAUVE), a wide-field spectrometer and imager conceived during the inaugural NASA Astrophysics Mission…
Extent of the Magnetotail of Venus From the Solar Orbiter, Parker Solar Probe and BepiColombo Flybys
Niklas J. T. Edberg, David J. Andrews, J. Jordi Boldú +20
We analyze data from multiple flybys by the Solar Orbiter, BepiColombo, and Parker Solar Probe (PSP) missions to study the interaction between Venus' plasma environment and the sol…
The assembly, characterization, and performance of SISTINE
Nicholas Nell, Kevin France, Nicholas Kruczek +6
The Suborbital Imaging Spectrograph for Transition region Irradiance from Nearby Exoplanet host stars (SISTINE) is a rocket-borne ultraviolet (UV) imaging spectrograph designed to…
A solar rotation signature in cosmic dust: frequency analysis of dust particle impacts on the Wind spacecraft
Lennart R. Baalmann, Silvan Hunziker, Arthur Péronne +7
Dust particle impacts on the Wind spacecraft were detected with its plasma wave instrument Wind/WAVES. Frequency analysis on this dust impact time series revealed spectral peaks in…
High-energy spectra of LTT 1445A and GJ 486 reveal flares and activity
H. Diamond-Lowe, G. W. King, A. Youngblood +19
The high-energy radiative output, from the X-ray to the ultraviolet, of exoplanet host stars drives photochemical reactions and mass loss in the upper regions of planetary atmosphe…
A Benchmark JWST Near-Infrared Spectrum for the Exoplanet WASP-39b
A. L. Carter, E. M. May, N. Espinoza +77
Observing exoplanets through transmission spectroscopy supplies detailed information on their atmospheric composition, physics, and chemistry. Prior to JWST, these observations wer…
Sulphur dioxide in the mid-infrared transmission spectrum of WASP-39b
Diana Powell, Adina D. Feinstein, Elspeth K. H. Lee +70
The recent inference of sulphur dioxide (SO) in the atmosphere of the hot (1100 K), Saturn-mass exoplanet WASP-39b from near-infrared JWST observations suggests that phot…
Energetic proton losses reveal Io's extended and longitudinally asymmetrical atmosphere
H. L. F. Huybrighs, C. P. A. van Buchem, A. Blöcker +3
Along the I24, I27 and I31 flybys of Io (1999-2001), the Energetic Particle Detector (EPD) onboard the Galileo spacecraft observed localised regions of energetic protons losses (15…
Simultaneous spectropolarimetric observations in the H and Ca II 8662 Å lines of an active region
Harsh Mathur, K. Nagaraju, Rahul Yadav +1
We present spectropolarimetric observations of an active region recorded simultaneously in the H Ca II 8662 Å lines. The sunspot exhibits multiple structures, including a lightb…
The COS-Holes Survey: Connecting Galaxy Black Hole Mass with the State of the CGM
Samantha L. Garza, Jessica K. Werk, Benjamin D. Oppenheimer +9
We present an analysis of \textit{HST}/COS/G160M observations of CIV in the inner circumgalactic medium (CGM) of a novel sample of eight z0, LL galaxies, p…
Interpolation and synthesis of sparse samples in exoplanet atmospheric modeling
Jacob Haqq-Misra, Eric T. Wolf, Thomas J. Fauchez +1
This paper highlights methods from geostatistics that are relevant to the interpretation, intercomparison, and synthesis of atmospheric model data, with a specific application to e…
First direct observations of interplanetary shock impact angle effects on actual geomagnetically induced currents: The case of the Finnish natural gas pipeline system
Denny M. Oliveira, Eftyhia Zesta, Sergio Vidal-Luengo
The impact of interplanetary (IP) shocks on the Earth's magnetosphere can greatly disturb the geomagnetic field and electric currents in the magnetosphere-ionosphere system. At hig…
