Isotopic constraints on lightning as a source of fixed nitrogen in Earth's early biosphere
Patrick Barth, Eva E. Stüeken, Christiane Helling +4
Bioavailable nitrogen is thought to be a requirement for the origin and sustenance of life. Before the onset of biological nitrogen fixation, abiotic pathways to fix atmospheric N2…
Anoxic Atmospheres on Mars Driven by Volcanism: Implications for Past Environments and Life
Steven F. Sholes, Megan L. Smith, Mark W. Claire +2
Mars today has no active volcanism and its atmosphere is oxidizing, dominated by the photochemistry of CO2 and H2O. Using a one-dimensional photochemical model, we consider whether…
ESA Voyage 2050 White Paper: Detecting life outside our solar system with a large high-contrast-imaging mission
Ignas Snellen, Simon Albrecht, Guillem Anglada-Escude +64
In this white paper, we recommend the European Space Agency plays a proactive role in developing a global collaborative effort to construct a large high-contrast imaging space tele…
Long Term Planetary Habitability and the Carbonate-Silicate Cycle
Andrew J. Rushby, Martin Johnson, Benjamin J. W. Mills +2
The potential habitability of an exoplanet is traditionally assessed by determining if its orbit falls within the circumstellar `habitable zone' of its star, defined as the distanc…
The Pale Orange Dot: The Spectrum and Habitability of Hazy Archean Earth
Giada Arney, Shawn D. Domagal-Goldman, Victoria S. Meadows +6
Recognizing whether a planet can support life is a primary goal of future exoplanet spectral characterization missions, but past research on habitability assessment has largely ign…
The Need for Laboratory Work to Aid in The Understanding of Exoplanetary Atmospheres
Jonathan J. Fortney, Tyler D. Robinson, Shawn Domagal-Goldman +31
Advancements in our understanding of exoplanetary atmospheres, from massive gas giants down to rocky worlds, depend on the constructive challenges between observations and models.…
Abiotic Ozone and Oxygen in Atmospheres Similar to Prebiotic Earth
Shawn D. Domagal-Goldman, Antígona Segura, Mark W. Claire +2
The search for life on planets outside our solar system will use spectroscopic identification of atmospheric biosignatures. The most robust remotely-detectable potential biosignatu…
Using Dimers to Measure Biosignatures and Atmospheric Pressure for Terrestrial Exoplanets
Amit Misra, Victoria Meadows, Mark Claire +1
We present a new method to probe atmospheric pressure on Earthlike planets using (O2-O2) dimers in the near-infrared. We also show that dimer features could be the most readily det…
Ensemble Properties of Comets in the Sloan Digital Sky Survey
Michael Solontoi, Zeljko Ivezic, Mario Juric +10
We present the ensemble properties of 31 comets (27 resolved and 4 unresolved) observed by the Sloan Digital Sky Survey (SDSS). This sample of comets represents about 1 comet per 1…
LSST Science Book, Version 2.0
LSST Science Collaboration, Paul A. Abell, Julius Allison +245
A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade.…
Training the Next Generation of Astronomers
Peter K. G. Williams, Eric Huff, Holly Maness +28
While both society and astronomy have evolved greatly over the past fifty years, the academic institutions and incentives that shape our field have remained largely stagnant. As a…
Stellar SEDs from 0.3-2.5 Microns: Tracing the Stellar Locus and Searching for Color Outliers in SDSS and 2MASS
Kevin R. Covey, Zeljko Ivezic, David J. Schlegel +15
The Sloan Digital Sky Survey (SDSS) and Two Micron All Sky Survey (2MASS) are rich resources for studying stellar astrophysics and the structure and formation history of the Galaxy…
The UV, Optical, and IR Properties of SDSS Sources Detected by GALEX
Marcel A. Agueros, Zeljko Ivezic, Kevin R. Covey +18
We discuss the UV, optical, and IR properties of the SDSS sources detected by GALEX as part of its All-sky Imaging Survey Early Release Observations. Virtually all of the GALEX sou…
