planetplanet

planetplanet photodynamical code

In my latest paper, I showed that planet-planet occultations are extremely common in the TRAPPIST-1 system. Detections of these events with JWST will constrain the 3D architecture of the system and simple properties of the planet surfaces. Below I make available the code I developed for predicting and modeling planet-planet occultations, as well as transit and secondary eclipse light curves, phase curves, mutual transits, and more.

exoaurora

pale green dot aurorae on proxima b

In this paper, I showed how auroral emission from the habitable zone planet Proxima Centauri b can be used to characterize its orbital properties, its mass, and its atmospheric composition.

trappist1

trappist-1 search for planet h

I used data from K2 to confirm the period of TRAPPIST-1h, measure the rotation period of the star, and establish that all seven planets in TRAPPIST-1 are in three-body Laplace resonances.

mirage

mirage earths m dwarf water loss

In this paper, I showed how the extended pre-main sequence phase of M dwarfs can lead to extreme water loss and the possible buildup of oxygen in the atmospheres of terrestrial planets in the habitable zones of these stars.

about

about about rodrigo

I'm currently a postdoc at UW in Seattle, working on finding novel ways to detect and characterize exoplanets, particularly those in the habitable zone. I mainly work with light curves from the K2 mission, and I'm gearing up to tackle science with TESS and JWST. Outside the office I love to hike, bike, swim, craft lattes, faulty parallelism, and oxford commas.
everest

everest k2 precision photometry

everest is an open-source pipeline for removing instrumental noise from light curves generated by K2. The code exploits correlations across the pixels on the Kepler CCD to remove systematics introduced by the spacecraft's pointing error, yielding light curves with precision comparable to that of the original Kepler mission.

hecs

hecs habitable evaporated cores

The extended pre-main sequence phase of M dwarfs can drive vigorous hydrodynamic escape from their planets. In this paper, I showed how in some cases, small, gas-rich planets can lose their hydrogen envelopes and form HECs.

vplanet

vplanet the virtual planet

VPLANET models the evolution of potentially habitable planets from their formation to the present day, accounting for processes such as stellar evolution, atmospheric escape, climate evolution, etc.
