Biases in the Transit, Radial velocity, Gravitational Microlensing, and direct Imaging exoplanet discovery methods

Journal of high school science
The field of extrasolar planets or exoplanets, planets in star systems outside of the solar system, is a relatively new field of astronomy emerging in the late 20th century.

A sub-Neptune exoplanet with a low-metallicity methane-depleted atmosphere and Mie-scattering clouds

Nature Astronomy, 2019
With no analogues in the Solar System, the discovery of thousands of exoplanets with masses and radii intermediate between Earth and Neptune was one of the big surprises of exoplanet science.

Democratizing and Enhancing Exoplanet Research with the Unistellar Citizen Science Network and Astronomy Modeling Instruction

This thesis explores the potential in democratizing and augmenting exoplanet research via citizen science by utilizing a global network of portable image-intensified computerized telescopes, and inquiry-based astronomy instruction. A central objective is to establish that citizen scientists, using exoplanet transit photometry with compact, connected ...

Software Development within STScI’s TIKE Server to Increase Accessibility of TESS Exoplanet Transit Data to Introductory Astronomy Students

A sorely underutilized tool in teaching astronomy concepts to new students of astronomy are exoplanet transits. They have the potential to be easy to understand, while demonstrating the concepts of light curves, creating time-series data from a single pixel, how Kepler’s laws can be practically used, and generally how astronomers are able to imply a ...
