The Interstellar Laser Beacons Hypothesis and the Cosmic Lighthouses Project
Daniel Apai, Chia-Lung Lin, Kevin Wagner
The paper proposes that low‑cost, long‑lived pulsed laser beacons with microsecond to millisecond durations are optimal for interstellar communication, and that recent advances in…
Direct Imaging Discovery of Giant Exoplanet Pictoris d: A Decade-Long Game of Hide-and-Seek
Ben J. Sutlieff, Markus J. Bonse, Valentin Christiaens +94
The paper reports the direct imaging discovery of a third giant exoplanet, β Pictoris d, using VLT/ERIS and archival JWST/NIRCam and VLT/SPHERE data, and characterizes its orbit, t…
Nautilus Space Observatory: The Evolution of Planets and their Atmospheres
Ilaria Pascucci, Noah Tuchow, Yifan Zhou +11
We are just beginning to explore the billion-year evolution from nascent planets in disks to mature planetary systems. Recent discoveries hint at demographic and atmospheric differ…
Time-variable Scattered Light in Herbig Disks Observed with Subaru/SCExAO
Camryn Mullin, Miles Lucas, Ruobing Dong +12
Using the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument, we present near-infrared K-band polarimetric imaging of nine Herbig stars selected from a volume-limited…
Forecasting Catastrophe: Constraints on the Fomalhaut Main Belt Planetesimal Population from Observed Collisional Remnants
Arin M. Avsar, Kevin Wagner, Dániel Apai +2
Catastrophic planetesimal disruptions offer a unique opportunity to study and characterize large planetesimal populations in exoplanetary systems that are not currently detectable…
Are We There Yet? Challenges in Quantifying the Frequency of Earth Analogs in the Habitable Zone
Rachel B. Fernandes, Samson Johnson, Galen J. Bergsten +43
Searching for life elsewhere in the universe is one of the most highly prioritized pursuits in astronomy today. However, the ability to observe evidence of Earth-like life through…
