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. […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, , , , | Summary: Handedness, or chirality, has been a continuing source of inspiration across a wide range of scientific problems. After a quick review of some important, instructive historical examples, I present three contemporary case studies involving sophisticated applications of chirality at the […]
Kavli Affiliate: Sara Seager | First 5 Authors: Sara Seager, Janusz J. Petkowski, Christopher E. Carr, David Grinspoon, Bethany Ehlmann | Summary: The Venus Life Finder Missions are a series of focused astrobiology mission concepts to search for habitability, signs of life, and life itself in the Venus atmosphere. While people have speculated on life […]
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 […]
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 […]

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 […]
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 […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Martin C. Weisskopf, Paolo Soffitta, Luca Baldini, Brian D. Ramsey, Stephen L. O’Dell | Summary: Scheduled to launch in late 2021, the Imaging X-ray Polarimetry Explorer (IXPE) is a NASA Small Explorer Mission in collaboration with the Italian Space Agency (ASI). The mission will open a […]
