Semi-Empirical Modeling of the Atmospheres of the M Dwarf Exoplanet Hosts GJ 832 and GJ 581
Dennis Tilipman, Mariela Vieytes, Jeffrey L. Linsky +2
Stellar ultraviolet (UV) radiation drives photochemistry, and extreme-ultraviolet (EUV) radiation drives mass loss in exoplanet atmospheres. However, the UV flux is partly unobserv…
Switchbacks: statistical properties and deviations from alfvénicity
A. Larosa, V. Krasnoselskikh, T. Dudok de Witınst +16
{Parker Solar Probe's first solar encounter has revealed the presence of sudden magnetic field deflections that are called switchbacks and are associated with proton velocity enhan…
Observations of Energized Electrons in the Martian Magnetosheath
K. Horaites, L. Andersson, S. J. Schwartz +5
This observational study demonstrates that the magnitude and location of energization of electrons in the Martian magnetosheath is more complex than previous studies suggest. Elect…
Effects of Spin-Orbit Resonances and Tidal Heating on the Inner Edge of the Habitable Zone
Christopher M. Colose, Jacob Haqq-Misra, Eric T. Wolf +4
Much attention has been given to the climate dynamics and habitable boundaries of synchronously rotating planets around low mass stars. However, other rotational states are possibl…
Upper Atmosphere Smoke Injection from Large Areal Fires
Stephanie Redfern, Julie K. Lundquist, Owen B. Toon +3
Large fires can inject smoke into the upper troposphere and lower stratosphere. Detailed fire simulations allow for assessment of how local weather interacts with these fires and a…
Photodissociation Region Diagnostics Across Galactic Environments
Thomas G. Bisbas, Jonathan C. Tan, Kei E. I. Tanaka
We present three-dimensional astrochemical simulations and synthetic observations of magnetised, turbulent, self-gravitating molecular clouds. We explore various galactic interstel…
Forbidden atomic oxygen emissions in the Martian dayside upper atmosphere
Susarla Raghuram, Sonal Kumar Jain, Anil Bhardwaj
Recently, Nadir and Occultation for Mars Discovery (NOMAD) ultraviolet and visible spectrometer instrument on board the European Space Agency's ExoMars Trace Gas Orbiter (TGO) simu…
GJ 436b and the stellar wind interaction: simulations constraints using Ly and H transits
C. Villarreal D'Angelo, A. A. Vidotto, A. Esquivel +2
The GJ 436 planetary system is an extraordinary system. The Neptune-size planet that orbits the M3 dwarf revealed in the Ly line an extended neutral hydrogen atmosphere. This ma…
Black Hole Mass Measurements of Radio Galaxies NGC 315 and NGC 4261 Using ALMA CO Observations
Benjamin D. Boizelle, Jonelle L. Walsh, Aaron J. Barth +6
We present Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 5 and Cycle 6 observations of CO(21) and CO(32) emission at 0.2''0.3'' resolution in two radio-bright,…
In situ evidence of ion acceleration between consecutive reconnection jet fronts
Filomena Catapano, Alessandro Retino, Gaetano Zimbardo +21
Processes driven by unsteady reconnection can efficiently accelerate particles in many astrophysical plasmas. An example are the reconnection jet fronts in an outflow region. We pr…
Encounter of Parker Solar Probe and a Comet-like Object During Their Perihelia: Model Predictions and Measurements
Jiansen He, Bo Cui, Liping Yang +15
Parker Solar Probe (PSP) aims at exploring the nascent solar wind close to the Sun. Meanwhile, PSP is also expected to encounter small objects like comets and asteroids. In this wo…
The Second Data Release of the Survey of the MAgellanic Stellar History (SMASH)
David L. Nidever, Knut Olsen, Yumi Choi +32
The Large and Small Magellanic Clouds (LMC and SMC) are the largest satellite galaxies of the Milky Way and close enough to allow for a detailed exploration of their structure and…
The Dynamics of a High Mach Number Quasi-Perpendicular Shock: MMS Observations
H. Madanian, M. I. Desai, S. J. Schwartz +12
Shock parameters at Earth's bow shock in rare instances can approach the Mach numbers predicted at supernova remnants. We present our analysis of a high Alfvén Mach number ($M_A= 2…
HD 63021: Chromospheric Activity and Mass Transfer in a Close Binary
D. G. Whelan, S. D. Chojnowski, J. Labadie-Bartz +13
Prompted by X-ray detections from multiple surveys, we investigated the A-type star HD 63021 and found that it is a double-lined spectroscopic binary with highly variable emission…
The Photospheric Temperatures of Betelgeuse during the Great Dimming of 2019/2020: No New Dust Required
Graham M Harper, Edward F Guinan, Richard Wasatonic +1
The processes that shape the extended atmospheres of red supergiants (RSGs), heat their chromospheres, create molecular reservoirs, drive mass loss, and create dust remain poorly u…
Observability of ultraviolet N I lines in the atmosphere of transiting Earth-like planets
Mitchell E. Young, Luca Fossati, Colin Johnstone +5
Nitrogen is a biosignature gas that cannot be maintained in its Earth-like ratio with CO under abiotic conditions. It has also proven to be notoriously hard to detect at optica…
New Horizons Observations of the Cosmic Optical Background
Tod R. Lauer, Marc Postman, Harold A. Weaver +26
We used existing data from the New Horizons LORRI camera to measure the optical-band () sky brightness within seven high galactic latitude fields. T…
The Effect of Land Albedo on the Climate of Land-Dominated Planets in the TRAPPIST-1 System
Andrew J. Rushby, Aomawa L. Shields, Eric T. Wolf +2
Variations in the reflective properties of the bulk material that comprises the surface of land-dominated planets will affect the planetary energy balance by interacting differentl…
