Exoplanets and the Search for Life
Like Duolingo, but for Exoplanets and the Search for Life. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.

Key ideas in Exoplanets and the Search for Life
- Limb darkening makes the stellar edges appear cooler and dimmer than the center
- Gravitational interactions between planets cause departures from strict Keplerian periodicity
- Ignoring the 'softened' edges of the light curve leads to an underestimation of the planet-to-star radius ratio
- The magnitude and frequency of timing shifts can be used to solve for the mass and orbit of an unseen perturber
- The impact is wavelength-dependent, being more pronounced in shorter (bluer) wavelengths
- TTVs are most sensitive to planets near mean-motion resonances
- How limb darkening impacts the calculation of a planet's physical size
- The capability of TTVs to reveal hidden planets
- Gaussian Processes (GP) use kernels to model the covariance of stellar activity without over-fitting the transit signal
- The planet first hides the blue-shifted (approaching) half of the star, causing a redshift anomaly
- Stellar spots rotating in and out of view create correlated noise that mimics or masks transit depths
- The planet then crosses the stellar center where the rotational velocity component is zero
- The sequence of radial velocity shifts during the Rossiter-McLaughlin effect
- The secondary eclipse occurs when the planet passes behind the star, causing the system's total flux to drop
- Stellar noise and Gaussian Processes
- The depth of the eclipse in infrared wavelengths represents the planet's dayside thermal emission

Eight weeks. You meant to finish. You didn't.
Tomo gives Exoplanets and the Search for Life the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
