The Habitable Exoplanet Observatory (HabEx) Mission Concept Study Final Report
read the original abstract
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 sufficiently to enable an affordable space-based telescope mission capable of discovering and characterizing Earthlike planets orbiting nearby bright sunlike stars in order to search for signs of habitability and biosignatures. Such a mission can also be equipped with instrumentation that will enable broad and exciting general astrophysics and planetary science not possible from current or planned facilities. HabEx is a space telescope with unique imaging and multi-object spectroscopic capabilities at wavelengths ranging from ultraviolet (UV) to near-IR. These capabilities allow for a broad suite of compelling science that cuts across the entire NASA astrophysics portfolio. HabEx has three primary science goals: (1) Seek out nearby worlds and explore their habitability; (2) Map out nearby planetary systems and understand the diversity of the worlds they contain; (3) Enable new explorations of astrophysical systems from our own solar system to external galaxies by extending our reach in the UV through near-IR. This Great Observatory science will be selected through a competed GO program, and will account for about 50% of the HabEx primary mission. The preferred HabEx architecture is a 4m, monolithic, off-axis telescope that is diffraction-limited at 0.4 microns and is in an L2 orbit. HabEx employs two starlight suppression systems: a coronagraph and a starshade, each with their own dedicated instrument.

Fundamental Noise Limits of Infrared Detectors in the Presence of Readout Glow
Readout glow, not only 1/f drift, explains why averaging many non-destructive reads gives less noise reduction than 1/sqrt(N), and it sets a floor sigma_min ~ 1.5 sigma_RN^{1/2} G^{1/4}.

Combining a Diffraction-Limited Coronagraph with Fiber Nulling: A Demonstration of Serially Coupling Different Nullers
Experimental serial coupling of 1DDLC coronagraph and PFN achieves 3.5e-5 contrast at 6% wavelength offset, 20x better than coronagraph alone.

A Fast and Physically Grounded Ocean Model for GCMs: The Dynamical Slab Ocean Model of the Generic-PCM (rev. 3423)
A new dynamical slab ocean model incorporates Ekman transport via Sverdrup balance and Gent-McWilliams eddies to produce first-order matching ocean heat transport and improved Earth climate metrics at nearly zero extra cost.

Bioverse: Assessing the Ability of Direct Imaging Surveys to Empirically Constrain the Habitable Zone via Trends in Albedo
An HWO-like survey needs about 30 Earth-sized planets to recover a strong albedo step at the habitable zone, but 80-90 for weaker trends.

Identifying and Distinguishing Quenching Galaxies with Spatially Resolved Star Formation in Mock CASTOR and NGRST Observations
Mock CASTOR and NGRST images of TNG50 galaxies recover spatially resolved star formation well enough for machine-learning classification of inside-out versus outside-in quenching.

Impact of Climate States and Seasons on Future Exo-Earth Observations
Climate states on exoplanets with the same atmospheric composition create different reflectance spectra, changing the detectability of atmospheric features and biosignatures, with seasonal variations on high-obliquity...

Characterizing Earth analogs may require a moderate or high-resolution spectrograph
A template-matching simulation framework shows that R>1,000 spectrographs yield higher biosignature sensitivity than R~140 for Earth analogs, because correlated speckle noise can suppress detections at low resolution.

Characterizing Earth analogs may require a moderate or high-resolution spectrograph
Moderate to high spectral resolution (R>1000) provides higher sensitivity for detecting key molecules like H2O and O2 in Earth analogs than low resolution (R~140), as correlated speckle noise can suppress detections a...

Observational Tests of Terrestrial Planet Buffering Feedbacks and the Habitable Zone Concept
The paper's reported sample sizes for detecting climate buffering feedbacks are not supported because the simulations compare subsets to the full sample they came from and lack a control, making the numbers an artifac...

A Revised Mass and Period for the Habitable Zone super-Earth GJ 3378b: A Planet Straddling the Cosmic Shoreline
Joint radial-velocity analysis revises GJ 3378b's period to 21.45 days and minimum mass to 2.3 Earth masses, placing the habitable-zone planet near the cosmic shoreline.

The effect of spectral resolution on biosignature detection via reflected light observations of the Earth through time
Nominal HWO resolutions suffice to detect key biosignatures across Archean to Phanerozoic Earth atmospheres, with O3 enabling indirect low-O2 detection and NIR resolution preventing CO2-CO false positives.

Not Earth-like Yet Temperate? More Generic Climate Feedback Configurations Still Allow Temperate Climates in Habitable Zone Exo-Earth Candidates
An idealized model with an extra generalized feedback produces chaotic and runaway climates and predicts that strong positive fourth feedbacks reduce long-term temperate habitability of Earth-like exoplanets.
