Wind-driven Exclusion of Cosmic Rays in the Protoplanetary Disk Environment
L. Ilsedore Cleeves, Edwin A. Bergin, Fred C. Adams
The recent (apparent) passage of the Voyager 1 spacecraft into interstellar space provides us with front-row seats to the complex interplay between the solar wind and the protectiv…
Constraining the X-ray and Cosmic Ray Ionization Chemistry of the TW Hya Protoplanetary Disk: Evidence for a Sub-interstellar Cosmic Ray Rate
L. Ilsedore Cleeves, Edwin A. Bergin, Chunhua Qi +2
We present an observational and theoretical study of the primary ionizing agents (cosmic rays and X-rays) in the TW Hya protoplanetary disk. We use a set of resolved and unresolved…
Detections of trans-Neptunian ice in protoplanetary disks
M. K. McClure, C. Espaillat, N. Calvet +6
We present Herschel Space Observatory PACS spectra of T Tauri stars, in which we detect amorphous and crystalline water ice features. Using irradiated accretion disk models, we det…
The ancient heritage of water ice in the solar system
L. Ilsedore Cleeves, Edwin A. Bergin, Conel M. O'D. Alexander +4
Identifying the source of Earth's water is central to understanding the origins of life-fostering environments and to assessing the prevalence of such environments in space. Water…
Exclusion of Cosmic Rays in Protoplanetary Disks. II. Chemical Gradients and Observational Signatures
L. I. Cleeves, Edwin A. Bergin, Fred C. Adams
The chemical properties of protoplanetary disks are especially sensitive to their ionization environment. Sources of molecular gas ionization include cosmic rays, stellar X-rays an…
Exploring the Origins of Carbon in Terrestrial Worlds
Edwin A. Bergin, L. Ilsedore Cleeves, Nathan Crockett +1
Given the central role of carbon in the chemistry of life, it is a fundamental question as to how carbon is supplied to the Earth, in what form and when. We provide an accounting o…
