Could the Magnetic Star HD 135348 Possess a Rigidly Rotating Magnetosphere?

Kavli Affiliate: George R. Ricker | First 5 Authors: Rahul Jayaraman, Swetlana Hubrig, Daniel L. Holdsworth, Markus Schöller, Silva Järvinen | Summary: We report the detection and characterization of a new magnetospheric star, HD 135348, based on photometric and spectropolarimetric observations. The TESS light curve of this star exhibited variations consistent with stars known to […]

What’s Behind the Elephant’s Trunk? Identifying Young Stellar Objects on the Outskirts of IC1396

Kavli Affiliate: David A. Principe | First 5 Authors: Steven M. Silverberg, Hans Moritz Guenther, Jinyoung Serena Kim, David A. Principe, Scott J. Wolk | Summary: Empirically, the estimated lifetime of a typical protoplanetary disk is $<5-10$ Myr. However, the disk lifetimes required to produce a variety of observed exoplanetary systems may exceed this timescale. […]

First results on SiSeRO (Single electron Sensitive Read Out) devices — a new X-ray detector for scientific instrumentation

Kavli Affiliate: Marshall Bautz | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Barry Burke, Kevan Donlon, Gregory Prigozhin | Summary: We present an evaluation of a novel on-chip charge detector, called the Single electron Sensitive Read Out (SiSeRO), for charge-coupled device (CCD) image sensor applications. It uses a p-MOSFET transistor at the output stage with […]

Evidence for a Compact Object in the Aftermath of the Extra-Galactic Transient AT2018cow

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Dheeraj R. Pasham, Wynn C. G. Ho, William Alston, Ronald Remillard, Mason Ng | Summary: The brightest Fast Blue Optical Transients (FBOTs) are mysterious extragalactic explosions that may represent a new class of astrophysical phenomena. Their fast time to maximum brightness of less than a week […]

The TESS Faint Star Search: 1,617 TOIs from the TESS Primary Mission

Kavli Affiliate: George Ricker | First 5 Authors: Michelle Kunimoto, Tansu Daylan, Natalia Guerrero, William Fong, Steve Bryson | Summary: We present the detection of 1,617 new transiting planet candidates, identified in the Transiting Exoplanet Survey Satellite (TESS) full-frame images (FFIs) observed during the Primary Mission (Sectors 1 – 26). These candidates were initially detected […]

GJ 367b: A dense ultra-short period sub-Earth planet transiting a nearby red dwarf star

Kavli Affiliate: George R. Ricker | First 5 Authors: Kristine W. F. Lam, Szilárd Csizmadia, Nicola Astudillo-Defru, Xavier Bonfils, Davide Gandolfi | Summary: Ultra-short-period (USP) exoplanets have orbital periods shorter than one day. Precise masses and radii of USPs could provide constraints on their unknown formation and evolution processes. We report the detection and characterization […]
