Constraining the magnetic field on white dwarf surfaces; Zeeman effects and fine structure constant variation
J. Hu, J. K. Webb, T. R. Ayres +12
White dwarf atmospheres are subjected to gravitational potentials around times larger than occur on Earth. They provide a unique environment in which to search for any possi…
Doppler Events in the Solar Photosphere: The Coincident Superposition of Fast Granular Flows and p-mode Coherence Patches
R. Lee McClure, Mark P. Rast, Valentin MartınezPillet
Observations of the solar photosphere show spatially-compact large-amplitude Doppler velocity events with short lifetimes. In data from the Imaging Magnetograph eXperiment (IMaX) o…
On the generation of probabilistic forecasts from deterministic models
Enrico Camporeale, Xiangning Chu, Oleksiy Agapitov +1
Most of the methods that produce space weather forecasts are based on deterministic models. In order to generate a probabilistic forecast, a model needs to be run several times sam…
K2 Observations of SN 2018oh Reveal a Two-Component Rising Light Curve for a Type Ia Supernova
G. Dimitriadis, R. J. Foley, A. Rest +145
We present an exquisite, 30-min cadence Kepler (K2) light curve of the Type Ia supernova (SN Ia) 2018oh (ASASSN-18bt), starting weeks before explosion, covering the moment of explo…
Photometric and Spectroscopic Properties of Type Ia Supernova 2018oh with Early Excess Emission from the 2 Observations
W. Li, X. Wang, J. Vinkó +160
Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
Heliospheric modulation of the interstellar dust flow on to Earth
Peter Strub, Veerle J. Sterken, Rachel Soja +3
Aims. Based on measurements by the Ulysses spacecraft and high-resolution modelling of the motion of interstellar dust (ISD) through the heliosphere we predict the ISD flow in the…
XUV Radiation from A-stars: Implications for Ultra-hot Jupiters
L. Fossati, T. Koskinen, J. D. Lothringer +3
Extremely irradiated, close-in planets to early-type stars might be prone to strong atmospheric escape. We review the literature showing that X-ray-to-optical measurements indicate…
The Near-Ultraviolet Continuum Radiation in the Impulsive Phase of HF/GF-Type dMe Flares I: Data
Adam F. Kowalski, John P. Wisniewski, Suzanne L. Hawley +8
We present NUV flare spectra from the Hubble Space Telescope/Cosmic Origins Spectrograph during two moderate-amplitude U-band flares on the dM4e star GJ 1243. These spectra are som…
Magnetism in the Early Universe
Tina Kahniashvili, Axel Brandenburg, Arthur Kosowsky +2
Blazar observations point toward the possible presence of magnetic fields over intergalactic scales of the order of up to Mpc, with strengths of at least G…
The Properties of the Solar Corona and Its Connection to the Solar Wind
Steven R. Cranmer, Amy R. Winebarger
The corona is a layer of hot plasma that surrounds the Sun, traces out its complex magnetic field, and ultimately expands into interplanetary space as the supersonic solar wind. Al…
The Evolution of K Blackbody-Like Continuum Radiation in the Impulsive Phase of dMe Flares
Adam F. Kowalski, Mihalis Mathioudakis, Suzanne L. Hawley
The near-ultraviolet and optical (white-light) continuum radiation in M dwarf flares exhibits a range of observed characteristics, suggesting that the amount of heating at large op…
Biosignature Anisotropy Modeled on Temperate Tidally Locked M-dwarf Planets
Howard Chen, Eric T. Wolf, Ravi Kopparapu +2
A planet's atmospheric constituents (e.g., O, O, HO, CO, CH, NO) can provide clues to its surface habitability, and may offer biosignature targets for r…
Seasonal, Solar Zenith Angle, and Solar Flux Variations of O in the Topside Ionosphere of Mars
Zachary Girazian, Paul Mahaffy, Yuni Lee +1
Using observations from MAVEN's Neutral Gas and Ion Mass Spectrometer (NGIMS), we characterize the seasonal, solar zenith angle (SZA), and solar flux dependent variations of the O$…
Collision fluctuations of lucky droplets with superdroplets
Xiang-Yu Li, Bernhard Mehlig, Gunilla Svensson +2
It was previously shown that the superdroplet algorithm for modeling the collision-coalescence process can faithfully represent mean droplet growth in turbulent clouds. But an open…
Atmospheric dynamics and the variable transit of KELT-9 b
P. Wilson Cauley, Evgenya L. Shkolnik, Ilya Ilyin +3
We present a spectrally and temporally resolved detection of the optical Mg I triplet at 7.8 in the extended atmosphere of the ultra-hot Jupiter KELT-9 b, adding to the list of…
Nightside Winds at the Lower Clouds of Venus with Akatsuki/IR2: Longitudinal, local time and decadal variations from comparison with previous measurements
Javier Peralta, Keishiro Muto, Ricardo Hueso +16
We present measurements of the wind speeds at the nightside lower clouds of Venus from observations by JAXA's mission Akatsuki during 2016, complemented with new wind measurements…
The MUSCLES Treasury Survey. V. FUV Flares on Active and Inactive M Dwarfs
R. O. Parke Loyd, Kevin France, Allison Youngblood +10
M dwarf stars are known for their vigorous flaring. This flaring could impact the climate of orbiting planets, making it important to characterize M dwarf flares at the short wavel…
