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…
Understanding Global Galactic Star Formation
Paul A. Scowen, Rolf Jansen, Matthew Beasley +9
We propose to the community a comprehensive UV/optical/NIR imaging survey of Galactic star formation regions to probe all aspects of the star formation process. The primary goal of…
The Star Formation Camera
Paul A. Scowen, Rolf Jansen, Matthew Beasley +21
The Star Formation Camera (SFC) is a wide-field (~15'x19, >280 arcmin^2), high-resolution (18x18 mas pixels) UV/optical dichroic camera designed for the Theia 4-m space-borne space…
Geoscience and the Search for Life Beyond the Solar System
Rory Barnes, Anat Shahar, Cayman Unterborn +11
How can scientists conclude with high confidence that an exoplanet hosts life? As telescopes come on line over the next 20 years that can directly observe photons from terrestrial…
External Photoevaporation of the Solar Nebula: Jupiter's Noble Gas Enrichments
Nikhil Monga, Steven Desch
We present a model explaining elemental enrichments in Jupiter's atmosphere, particularly the noble gases Ar, Kr, and Xe. While He, Ne and O are depleted, seven other elements show…
The early Solar System and its meteoritical witnesses
Emmanuel Jacquet, Cornelis Dullemond, Joanna DrÄ Å¼kowska +1
Meteorites, and in particular primitive meteorites (chondrites), are irreplaceable probes of the solar protoplanetary disk. We review their essential properties and endeavour to pl…
A Stellar Magnesium to Silicon ratio in the atmosphere of an exoplanet
Jorge A. Sanchez, Peter C. B. Smith, Krishna Kanumalla +17
The elemental compositions of exoplanets encode information about their formation environments and internal structures. While volatile ratios such as carbon-to-oxygen (C/O) are use…
Seismic and acoustic signals from the 2014 'Interstellar Meteor'
Benjamin Fernando, Pierrick Mialle, G öram Ekstr öm +4
We conduct a thorough analysis of seismic and acoustic data from the so-called `Interstellar Meteor' which entered the Earth's atmosphere off the coast of Papua New Guinea on 2014-…
