Characterizing Earth analogs may require a moderate or high-resolution spectrograph

Jean-Baptiste Ruffio, Sarah Steiger, Corey Spohn +16

A primary goal of the Habitable Worlds Observatory (HWO) is to detect and measure the abundance of biosignature molecules, such as water (H2O) and oxygen (O2), in the atmosphere of…

Data post-processing gain resulting from the patchy nature of speckles

Jean-Baptiste Ruffio, Laurent Pueyo

The data post-processing gain is an important parameter for exposure time calculations used to inform the design of the Habitable Worlds Observatory (HWO). Assuming azimuthally sym…

Identifying rocky planets and water worlds among sub-Neptune-sized exoplanets with the Habitable Worlds Observatory

Renyu Hu, Michiel Min, Max Millar-Blanchaer +15

Astronomers are debating whether the plentiful "sub-Neptune" exoplanets -- worlds a bit larger than Earth but smaller than Neptune -- are predominantly rocky planets, water-rich "o…
