Kavli Affiliate: David A. Principe | First 5 Authors: Gregory J. Herczeg, Yuguang Chen, Jean-Francois Donati, Andrea K. Dupree, Frederick M. Walter | Summary: Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time of […]
Kavli Affiliate: Sara Seager | First 5 Authors: Sara Seager, Janusz J. Petkowski, Jingcheng Huang, Zhuchang Zhan, Sai Ravela | Summary: Waste gas products from technological civilizations may accumulate in an exoplanet atmosphere to detectable levels. We propose nitrogen trifluoride (NF3) and sulfur hexafluoride (SF6) as ideal technosignature gases. Earth life avoids producing or using […]
Kavli Affiliate: Sara Seager | First 5 Authors: Ares Osborn, David J. Armstrong, Jorge Fernández Fernández, Henrik Knierim, Vardan Adibekyan | Summary: To date, thousands of planets have been discovered, but there are regions of the orbital parameter space that are still bare. An example is the short period and intermediate mass/radius space known as […]

Kavli Affiliate: George Clark | First 5 Authors: Ian J. Cohen, Chris Arridge, Abigail Azari, Chris Bard, George Clark | Summary: Heliophysics is the field that "studies the nature of the Sun, and how it influences the very nature of space – and, in turn, the atmospheres of planetary bodies and the technology that exists […]
Kavli Affiliate: George Clark | First 5 Authors: Ian J. Cohen, Dan Baker, Jacob Bortnik, Pontus Brandt, Jim Burch | Summary: The field of Heliophysics has a branding problem. We need an answer to the question: “What is Heliophysics?”, the answer to which should clearly and succinctly defines our science in a compelling way that […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Aaron B. Pearlman, Paul Scholz, Suryarao Bethapudi, Jason W. T. Hessels, Victoria M. Kaspi | Summary: Since fast radio bursts (FRBs) were discovered, their precise origins have remained a mystery. Multiwavelength observations of nearby FRB sources provide one of the best ways to make rapid progress […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Aaron B. Pearlman, Paul Scholz, Suryarao Bethapudi, Jason W. T. Hessels, Victoria M. Kaspi | Summary: The precise origins of fast radio bursts (FRBs) remain unknown. Multiwavelength observations of nearby FRB sources can provide important insights into the enigmatic FRB phenomenon. Here, we present results from […]
Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Laurel Kaye, Shreyas Vissapragada, Maximilian N. Gunther, Suzanne Aigrain, Thomas Mikal-Evans | Summary: We present ground and space-based photometric observations of TOI-270 (L231-32), a system of three transiting planets consisting of one super-Earth and two sub-Neptunes discovered by TESS around a bright (K-mag=8.25) M3V dwarf. The planets […]
Kavli Affiliate: John Richardson | First 5 Authors: Veerle J. Sterken, Silvan Hunziker, Kostas Dialynas, Jan Leitner, Maximilian Sommer | Summary: We discuss the synergies between heliospheric and dust science, the open science questions, the technological endeavors and programmatic aspects that are important to maintain or develop in the decade to come. In particular, we […]
