Radiative transfer (RT) models are critical in the interpretation of exoplanetary spectra, in simulating exoplanet climates, and when designing the specifications of future flagship observatories. However, most models differ in methodologies and inpu

Following the discovery of the first exoplanet candidate transiting a white dwarf (WD), a "white dwarf opportunity" for characterizing the atmospheres of terrestrial exoplanets around WDs is emerging. Large planet-to-star size ratios and hence large

The White Dwarf Opportunity: Robust Detections of Molecules in Earth-like Exoplanet Atmospheres with the James Webb Space Telescope

Autor: Eric E. Mamajek, Thea Kozakis, Lisa Kaltenegger, Ryan J. MacDonald, Nikole K. Lewis, Jonathan C. McDowell, Andrew Vanderburg

The near-term search for life beyond the solar system currently focuses on transiting planets orbiting small M dwarfs, and the challenges of detecting signs of life in their atmospheres. However, planets orbiting white dwarfs (WDs) would provide a un

High-resolution Spectra and Biosignatures of Earth-like Planets Transiting White Dwarfs

Autor: Zifan Lin, Thea Kozakis, Lisa Kaltenegger

With the first observations of debris disks as well as proposed planets around white dwarfs, the question of how rocky planets around such stellar remnants can be characterized and probed for signs of life becomes tangible. White dwarfs are similar i

Atmospheres and UV Environments of Earth-like Planets throughout Post-main-sequence Evolution

Autor: Thea Kozakis, Lisa Kaltenegger

Publikováno v: The Astrophysical Journal. 875:99

During the post-main sequence phase of stellar evolution the orbital distance of the habitable zone, which allows for liquid surface water on terrestrial planets, moves out past the system's original frost line, providing an opportunity for outer pla
