The language of exoplanet ranking metrics needs to change
Elizabeth Tasker, Joshua Tan, Kevin Heng +14
We have found many Earth-sized worlds but we have no way of determining if their surfaces are Earth-like. This makes it impossible to quantitatively compare habitability, and prete…
Radio Emission from Red-Giant Hot Jupiters
Yuka Fujii, David S. Spiegel, Tony Mroczkowski +5
When planet-hosting stars evolve off the main sequence and go through the red-giant branch, the stars become orders of magnitudes more luminous and, at the same time, lose mass at…
IAS15: A fast, adaptive, high-order integrator for gravitational dynamics, accurate to machine precision over a billion orbits
Hanno Rein, David S. Spiegel
We present IAS15, a 15th-order integrator to simulate gravitational dynamics. The integrator is based on a Gauß-Radau quadrature and can handle conservative as well as non-conserva…
CHARIS Science: Performance Simulations for the Subaru Telescope's Third-Generation of Exoplanet Imaging Instrumentation
Timothy D. Brandt, Michael W. McElwain, Markus Janson +21
We describe the expected scientific capabilities of CHARIS, a high-contrast integral-field spectrograph (IFS) currently under construction for the Subaru telescope. CHARIS is part…
Some inconvenient truths about biosignatures involving two chemical species on Earth-like exoplanets
Hanno Rein, Yuka Fujii, David S. Spiegel
The detection of strong thermochemical disequilibrium in the atmosphere of an extrasolar planet is thought to be a potential biosignature. In this article we present a new kind of…
Prospects for Detecting Oxygen, Water, and Chlorophyll on an Exo-Earth
Timothy D. Brandt, David S. Spiegel
The goal of finding and characterizing nearby Earth-like planets is driving many NASA high-contrast flagship mission concepts, the latest of which is known as the Advanced Technolo…
