Habitable Zones Around Massive Stars: From the Main Sequence to Supergiants
Devesh Nandal, Abraham Loeb
Massive stars dominate the feedback of young stellar populations, yet their ultraviolet fields and winds are often presumed to preclude Earth like habitability. We test this by map…
Increased and Varied Radiation during the Sun's Encounters with Cold Clouds in the last 10 million years
Merav Opher, Joe Giacalone, Abraham Loeb +7
Recent research raises the possibility that 3 and 7 million years ago, the Sun encountered massive clouds that shrank the heliosphere--the solar cocoon protecting our solar system-…
Rotation Period of 3I/ATLAS After Perihelion from Jet Position Angle Wobble and Photometric Variability
Toni Scarmato, Abraham Loeb
We determine the post-perihelion rotation period of 3I/ATLAS using two independent diagnostics: the temporal modulation of the position angle (PA) of a persistent jet-like feature,…
Is the Interstellar Object 3I/ATLAS Alien Technology?
Adam Hibberd, Adam Crowl, Abraham Loeb
At this early stage of its passage through our Solar System, 3I/ATLAS, the recently discovered interstellar interloper, has displayed various anomalous characteristics, determined…
Intercepting 3I/ATLAS at Closest Approach to Jupiter with the Juno spacecraft
Abraham Loeb, Adam Hibberd, Adam Crowl
The interstellar object 3I/ATLAS is expected to arrive at a distance of million (~au) from Jupiter on March 16, 2026. We show that appl…
Laser Interferometer Lunar Antenna (LILA): Advancing the U.S. Priorities in Gravitational-wave and Lunar Science
Karan Jani, Matthew Abernathy, Emanuele Berti +30
The Laser Interferometer Lunar Antenna (LILA) is a next-generation gravitational-wave (GW) facility on the Moon. By harnessing the Moon's unique environment, LILA fills a critical…
