The Habitable Exoplanet Observatory (HabEx) Mission Concept Study Final Report
B. Scott Gaudi, Sara Seager, Bertrand Mennesson +183
The Habitable Exoplanet Observatory, or HabEx, has been designed to be the Great Observatory of the 2030s. For the first time in human history, technologies have matured sufficient…
The Landscape of Undergraduate Astronomy and Astrophysics Degree Requirements
Kate Follette, Carl Ferkinhoff, Michael Foley +5
In this document we summarize the results of a survey of undergraduate degree-granting programs conducted by the 2024-2025 American Astronomical Society Education Committee's Subco…
Three Years of High-Contrast Imaging of the PDS 70 b and c Exoplanets at Hα with MagAO-X: Evidence of Strong Protoplanet Hα Variability and Circumplanetary Dust
Laird M. Close, Jared R. Males, Jialin Li +23
We present 3 years of high-contrast imaging of the PDS 70 b and c accreting protoplanets with the new extreme AO system MagAO-X as part of the MaxProtoPlanetS survey of H proto…
The Gray Needle: Large Grains in the HD 15115 Debris Disk from LBT/PISCES/Ks and LBTI/LMIRcam/L' Adaptive Optics Imaging
Timothy J. Rodigas, Philip M. Hinz, Jarron Leisenring +52
We present diffraction-limited \ks band and \lprime adaptive optics images of the edge-on debris disk around the nearby F2 star HD 15115, obtained with a single 8.4 m primary mirro…
Wide Separation Planets In Time (WISPIT): Discovery of a Gap H Protoplanet WISPIT 2b with MagAO-X
Laird M. Close, Richelle F. van Capelleveen, Gabriel Weible +34
Excellent (<25 mas) H images of the star TYC 5709-354-1 led to the discovery of a rare H protoplanet. This star was discovered by the WISPIT survey to have a large multi-…
Near-IR Polarized Scattered Light Imagery of the DoAr 28 Transitional Disk
Evan A. Rich, John P. Wisniewski, Satoshi Mayama +52
We present the first spatially resolved polarized scattered light H-band detection of the DoAr 28 transitional disk. Our two epochs of imagery detect the scattered light disk from…
