Probable detection of an eruptive filament from a superflare on a solar-type star
Kosuke Namekata, Hiroyuki Maehara, Satoshi Honda +20
Solar flares are often accompanied by filament/prominence eruptions ( K and cm), sometimes leading to coronal mass ejections (CMEs) that direct…
Parker Solar Probe evidence for the absence of whistlers close to the Sun to scatter strahl and regulate heat flux

We present high-resolution observations of a flaring event in the M8 dwarf vB 10 using the near-infrared Habitable zone Planet Finder (HPF) spectrograph on the Hobby Eberly Telesco…
Chandra revisits WR48a: testing colliding wind models in massive binaries
Svetozar A. Zhekov, Marc Gagne, Stephen L. Skinner
We present results of new Chandra High-Energy Transmission Grating (HETG) observations (2019 November - December) of the massive Wolf-Rayet (WR) binary WR 48a. Analysis of these hi…
Cosmological Constraints from Gas Mass Fractions of Massive, Relaxed Galaxy Clusters
Adam B. Mantz, Steven W. Allen, Rebecca E. A. Canning +14
We present updated cosmological constraints from measurements of the gas mass fractions () of massive, dynamically relaxed galaxy clusters. Our new data set has greater le…
Improving cosmological constraints from galaxy cluster number counts with CMB-cluster-lensing data: Results from the SPT-SZ survey and forecasts for the future
P. S. Chaubal, C. L. Reichardt, N. Gupta +40
We show the improvement to cosmological constraints from galaxy cluster surveys with the addition of CMB-cluster lensing data. We explore the cosmological implications of adding ma…
SDSS-IV MaStar: Theoretical Atmospheric Parameters for the MaNGA Stellar Library
Lewis Hill, Daniel Thomas, Claudia Maraston +16
We calculate the fundamental stellar parameters effective temperature, surface gravity and iron abundance - T, log g, [Fe/H] - for the final release of the Mapping Near…
Energy Dissipation in Turbulent Reconnection
R. Bandyopadhyay, A. Chasapis, W. H. Matthaeus +6
We study the nature of pressure-strain interaction at reconnection sites, detected by NASA's Magnetospheric Multiscale (MMS) Mission. We employ data from a series of published case…
3D Kinematics of Stellar SiO Masers in the Galactic Center
Jennie Paine, Jeremy Darling
We present 3D velocity measurements and acceleration limits for stars within a few parsec of the Galactic Center (GC) black hole, Sgr A*, based on observations of 43 and 86 GHz cir…
Shocks in the Stacked Sunyaev-Zel'dovich Profiles of Clusters II: Measurements from SPT-SZ + Planck Compton-y Map
D. Anbajagane, C. Chang, B. Jain +43
We search for the signature of cosmological shocks in stacked gas pressure profiles of galaxy clusters using data from the South Pole Telescope (SPT). Specifically, we stack the la…
