Clear and Cloudy Exoplanet Forecasts for JWST: Maps, Retrieved Composition, and Constraints on Formation with MIRI and NIRCam [PDF]

Astronomical Journal, 2018
The James Webb Space Telescope (JWST) will measure exoplanet transmission and eclipse spectroscopy at unprecedented precisions to better understand planet structure, dynamics, chemistry, and formation.

Photochemical Hazes Dramatically Alter Temperature Structure and Atmospheric Circulation in 3D Simulations of Hot Jupiters

The Astrophysical Journal, 2023
Photochemical hazes are expected to form in hot Jupiter atmospheres and may explain the strong scattering slopes and muted spectral features observed in the transmission spectra of many hot Jupiters.

On the protection of extrasolar Earth-like planets around K/M stars against galactic cosmic rays

, 2009
Previous studies have shown that extrasolar Earth-like planets in close-in habitable zones around M-stars are weakly protected against galactic cosmic rays (GCRs), leading to a strongly increased particle flux to the top of the planetary atmosphere.

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK

Journal of Research in Science Teaching, EarlyView.
ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

Exoplanet Predictions Based on the Generalised Titius-Bode Relation

, 2013
We evaluate the extent to which newly detected exoplanetary systems containing at least four planets adhere to a generalized Titius-Bode (TB) relation.

Lactea: Web‐Based Spectrum‐Preserving Multi‐Resolution Visualization of the GAIA Star Catalog

Computer Graphics Forum, EarlyView.
Abstract The explosion of data in astronomy has resulted in an era of unprecedented opportunities for discovery. The GAIA mission's catalog, containing a large number of light sources (mostly stars) with several parameters such as sky position and proper motion, is playing a significant role in advancing astronomy research and has been crucial in ...

A Dynamic Scheme to Assess Habitability of Exoplanets

, 2012
In the next few years, the number of catalogued exoplanets will be counted in the thousands and with it the need will arise to prioritize them in regard to habitability and the potential presence of life. Here, we suggest a first attempt of a dynamic scheme for classification based on our current understanding of parameters that are consistent and ...

Statistical Distribution Function of Orbital Spacings in Planetary Systems

The Astronomical Journal
The minimum orbital separation of planets in long-stable planetary systems is often modeled as a step function, parameterized with a single value ${{\rm{\Delta }}}_{\min }$ (measured in mutual Hill radius of the two neighboring planets).

Atmospheric Circulation of Terrestrial Exoplanets [PDF]

, 2013
The investigation of planets around other stars began with the study of gas giants, but is now extending to the discovery and characterization of super-Earths and terrestrial planets.
