![All plot facets identical to Figure 5. Simultaneous characterization of H2O and O2. Detector noise and thermal emission are included. Shorter wavelengths are preferred for dual detection, but result in lower yields. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/09/Possible-Observational.png?resize=1200%2C716&ssl=1)
[astro-ph.EP] We present a variety of possible observational sequences from planet detection to characterization (i.e., survey strategies) for the initial exoEarth detection and characterization survey phase of the Habitable Worlds […]

The Science Potential of Characterizing Gas Giant Exoplanets with HWO
[astro-ph.EP] With the ability to directly image Earth-like exoplanets and search their atmospheres for biosignatures, the upcoming Habitable Worlds Observatory (HWO) will also collect high signal-to-noise ratio (S/N) reflected-light photometry […]

Rotational Spectroscopy And Astronomical Search Of Propane-1-thiol (CH3CH2CH2SH) And Propane-2-thiol ((CH3)2CHSH)
[astro-ph.GA] This study focuses on propanethiol (or propyl mercaptan, C3H7SH), a sulfur analogue of propanol and a key target for investigating interstellar sulfur chemistry. We report the laboratory rotational spectroscopic […]
![Wavelength distributions of candidate spectral lines retained at each step of the line-selection procedure. The histograms show the initial linelist (light), lines retained after automated vetting (intermediate), and the final manually vetted sample (dark). The shaded background regions indicate approximate wavelength ranges for the Y, J, H, and K-bands.-- [astro-ph.SR]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/09/Elemental.png?resize=1200%2C716&ssl=1)

Elemental Abundances of Cool Stars: A Spectroscopic Framework Applied to Five Planet-Host Stars
[astro-ph.SR] Stellar elemental abundances provide important constraints on the chemical environments from which planets form. M and late-K dwarfs are prime targets for the characterization of small exoplanets, yet their […]

Local Constraints On Alcohol–Thioalcohol Analogs In G35.2N
[astro-ph.GA] The chemistry of sulfur-bearing complex organic molecules in dense star-forming environments remains uncertain, partly because the dominant sulfur reservoirs in dense gas and ices are poorly identified. Alcohol–thioalcohol pairs […]
