Kepler-80 Revisited: Assessing the Participation of a Newly Discovered Planet in the Resonant Chain

The Astronomical Journal, 2023
In this paper, we consider the chain of resonances in the Kepler-80 system and evaluate the impact that the additional member of the resonant chain discovered by Shallue & Vanderburg has on the dynamics of the system and the physical parameters that can ...

Emergent Spectral Fluxes of Hot Jupiters: An Abrupt Rise in Dayside Brightness Temperature Under Strong Irradiation

The Astronomical Journal, 2023
We study the emergent spectral fluxes of transiting hot Jupiters, using secondary eclipses from Spitzer. To achieve a large and uniform sample, we have reanalyzed all secondary eclipses for all hot Jupiters observed by Spitzer at 3.6 and/or 4.5 μ m.

New Astronomy Reviews special issue: History of Kepler’s major exoplanet “firsts” [PDF]

New Astronomy Reviews, 2018
NASA's Kepler Mission revolutionized exoplanet science in the early part of the 2010's. Looking back from the perspective of the end of that decade, Kepler appears to have burst upon the scene ready for battle, like Athena springing forth, fully formed, from the head of Zeus. The story was not so simple.

Using dimers to measure biosignatures and atmospheric pressure for terrestrial exoplanets [PDF]

, 2014
We present a new method to probe atmospheric pressure on Earth-like planets using (O-O) dimers in the near-infrared. We also show that dimer features could be the most readily detectable biosignatures for Earth-like atmospheres and may even be detectable

Exoplanets in physics and astronomy teaching

Revista Brasileira de Ensino de Ciência e Tecnologia, 2021
This article aims to investigate Physics teaching and scientific dissemination activities with the main theme being the study of exoplanets, planets belonging to a star system distinct from our solar system. The theoretical basis of the project involves reading and writing about articles, books, theses and dissertations focused on the themes of this ...
