High-Resolution Transmission Spectra of Earth through Geological Time

Model Spectra for Earth through geological time from 0.4 to 20 microns at a resolution > 100,000 for 5 epochs through Earth’s geological time from an anoxic atmosphere 3.9 Ga to an anoxic atmosphere with less CO2 and CH4 around 3.5 Ga and 3 models which capture the rise of oxygen from 0.01 PAL O2 to 1PAL (21% O2) on modern Earth, which started around 2.4 billion years ago (Ga).

High resolution reflection spectra for Proxima b and Trappist-1e models for ELT observations

Title: High-resolution reflection spectra for Proxima b and Trappist-1e models for ELT observations Authors: Zifan Lin & Lisa Kaltenegger Description: High-resolution reflection spectra of two of the closest potentially habitable exoplanets (Proxima b and Trappist-1e) for a range of terrestrial atmospheres and surface pressures for active and inactive phases of their host stars for both oxic and anoxic conditions.

Spectra, Albedos, and Colors of Solar System Bodies 

The geometric albedos and spectra for 19 Solar System bodies from 0.5 - 2.5 µm, including spectra at low resolution (R=8) and around F0, G0, K0, M0, and M9 stars. Color magnitudes are also included for all spectra. For more information see Madden & Kaltenegger 2018 in Astrobiology.
