Exoplanet detection from starshade images using convolutional neural networks

Optical Engineering + Applications, 2023
High-contrast, direct imaging of exoplanets is a key objective for the future of astronomy. Underpinning both the development and successful deployment of future direct imaging missions is the ability to analyze the resulting data. Therefore, in order to

Ozone-like layer in an exoplanet atmosphere [PDF]

Nature, 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 ...

The impending opacity challenge in exoplanet atmospheric characterization

Nature Astronomy, 2022
With a new generation of observatories coming online this decade, the process of characterizing exoplanet atmospheres will need to be reinvented. Currently mostly on the instrumental side, characterization bottlenecks will soon appear at the models used ...

A secondary atmosphere on the rocky Exoplanet 55 Cancri e.

Nature
Characterizing rocky exoplanets is a central endeavor of astronomy, and yet the search for atmospheres on rocky exoplanets has hitherto resulted in either tight upper limits on the atmospheric mass1-3 or inconclusive results4-6.

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

A benchmark JWST near-infrared spectrum for the exoplanet WASP-39 b

Nature Astronomy
Observing exoplanets through transmission spectroscopy supplies detailed information about their atmospheric composition, physics and chemistry. Before the James Webb Space Telescope (JWST), these observations were limited to a narrow wavelength range ...
