Ozone-like layer in an exoplanet atmosphere [PDF]

open access: possibleNature, 2017
The nature of exoplanetary atmospheres is hotly debated. The thermal spectrum of an exoplanet called a hot Jupiter reveals the presence of an analogue of Earth's ozone layer, although its composition is unknown. See Letter p.58 Earth's atmosphere consists of layers that are partially defined by ...

A Mars-sized exoplanet

Nature, 2015
Analysis of Kepler data has yielded the smallest known mass for an exoplanet orbiting a normal star. Its mass and size are similar to those of Mars, setting a benchmark for the properties of exoplanets smaller than Earth. See Letter p.321 Kepler-138, a red dwarf in the constellation of Lyra, hosts ...

A new spin on exoplanets

Nature, 2014
Spectroscopic observations of a young exoplanet have allowed its spin velocity to be directly measured. Its fast spin is in accord with the extrapolation of the known trend in spin velocity as a function of planet mass. See Letter p.63 Near-infrared spectroscopic observations of the young extrasolar

Exoplanet caught speeding

Nature, 2010
The masses of exoplanets have so far been inferred from the tiny gravitational pull they exert on the host stars. It is now possible to measure them from shifts in spectral lines arising from the planets' atmospheres.

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 ...
