X-ray grating spectroscopy as a mission enhancement
Hans Moritz Guenther, Ehud Behar, Joel N. Bregman +27
We propose to add instruments to any potential future X-ray mission with focussing optics that is considered in NASA's ASTRA framework. Such an instrument is a necessity to study A…
Photochemical hazes can trace the C/O ratio in exoplanet atmospheres
Lia Corrales, Lisseth Gavilan, D. J. Teal +1
Photochemical hazes are suspected to obscure molecular features, such as water, from detection in the transmission spectra of exoplanets with atmospheric temperatures < 800 K. The…
Oxygen and iron in interstellar dust: an X-ray investigation
I. Psaradaki, E. Costantini, D. Rogantini +9
Understanding the chemistry of the interstellar medium (ISM) is fundamental for the comprehension of the Galactic and stellar evolution. X-rays provide an excellent way to study th…
Interstellar absorption and dust scattering
Elisa Costantini, Lia Corrales
The study of the interstellar medium (ISM) in the X-rays has entered a golden age with the advent of the X-ray observatories XMM-Newton and Chandra. High-energy resolution allowed…

The Astropy Collaboration, Adrian M. Price-Whelan, Pey Lian Lim +133
The Astropy Project supports and fosters the development of open-source and openly-developed Python packages that provide commonly needed functionality to the astronomical communit…
The strongly irradiated planets in Praesepe
George W. King, Peter J. Wheatley, Victoria A. Fawcett +3
We present an analysis of XMM-Newton observations of four stars in the young (670 Myr) open cluster Praesepe. The planets hosted by these stars all lie close in radius-period space…
Five new hot-Jupiter transits investigated with Swift-UVOT
Lia Corrales, Sasikrishna Ravi, George W. King +3
Short wavelength exoplanet transit measurements have been used to probe mass-loss in exoplanet atmospheres. We present the Swift-UVOT transit light curves for five hot Jupiters orb…
The near-UV transit of HD 189733b with the XMM-Newton Optical Monitor
George W. King, Lía Corrales, Peter J. Wheatley +6
We present analysis of XMM-Newton Optical Monitor observations in the near-ultraviolet of HD 189733, covering twenty primary transits of its hot Jupiter planet. The transit is clea…
The high-energy spectrum of the nearby planet-hosting inactive mid-M dwarf LHS 3844
Hannah Diamond-Lowe, Allison Youngblood, David Charbonneau +5
To fully characterize the atmospheres, or lack thereof, of terrestrial exoplanets we must include the high-energy environments provided by their host stars. The nearby mid-M dwarf…
Great Observatories: The Past and Future of Panchromatic Astrophysics
L. Armus, S. T. Megeath, L. Corrales +30
NASA's Great Observatories have opened up the electromagnetic spectrum from space, providing sustained access to wavelengths not accessible from the ground. Together, Hubble, Compt…
Silicon X-ray absorption in the Galactic ISM: the gaseous component
E. Gatuzz, T. W. Gorczyca, M. F. Hasoglu +3
We present a detailed analysis of the gaseous component of the Si K edge using high-resolution Chandra spectra of low-mass X-ray binaries. We fit the spectra with amodified version…
The Chandra High Resolution X-ray Spectrum of Quiescent Emission from Sgr A*
L. Corrales, F. K. Baganoff, Q. D. Wang +7
In quiescence, Sgr A* is surprisingly dim, shining 100,000 times less than expected for its environment. This problem has motivated a host of theoretical models to explain radiativ…
Chandra Spectral and Timing Analysis of Sgr A*'s Brightest X-ray Flares
Daryl Haggard, Melania Nynka, Brayden Mon +17
We analyze the two brightest Chandra X-ray flares detected from Sagittarius A*, with peak luminosities more than 600 x and 245 x greater than the quiescent X-ray emission. The brig…
Astro2020 APC White Paper: Accessible Astronomy: Policies, Practices, and Strategies to Increase Participation of Astronomers with Disabilities
Alicia Aarnio, Nicholas Murphy, Karen Knierman +14
(Abridged) In this white paper, we outline the major barriers to access within the educational and professional practice of astronomy. We present current best practices for inclusi…
Astro2020 Science White Paper: Probing the Structure of Interstellar Dust from Micron to Kpc Scales with X-ray Imaging
Lynne Valencic, Lia Corrales, Sebastian Heinz +8
The X-ray regime is a largely underused resource for constraining interstellar dust grain models and improving our understanding of the physical processes that dictate how grains e…
Astro 2020: Astromineralogy of interstellar dust with X-ray spectroscopy
Lia Corrales, Lynne Valencic, Elisa Costantini +16
X-ray absorption fine structure (XAFS) in the 0.2-2 keV band is a crucial component in multi-wavelength studies of dust mineralogy, size, and shape -- parameters that are necessary…
High-Energy Photon and Particle Effects onExoplanet Atmospheres and Habitability
Jeremy J. Drake, Julián D. Alvarado-Gómez, Vladimir Airapetian +41
It is now recognized that energetic stellar photon and particle radiation evaporates and erodes planetary atmospheres and controls upper atmospheric chemistry. Key exoplanet host s…
Astro2020: How does dust escape from galaxies?
