Stellar Imager (SI): developing and testing a predictive dynamo model for the Sun by imaging other stars
Kenneth G. Carpenter, Carolus J. Schrijver, Margarita Karovska +39
The Stellar Imager mission concept is a space-based UV/Optical interferometer designed to resolve surface magnetic activity and subsurface structure and flows of a population of Su…
Million Degree Plasmas in Extreme Ultraviolet (EUV) Astrophysics
Michael P. Kowalski, Martin Barstow, Frederick Bruhweiler +12
Million degree plasmas are ubiquitous in the Universe, and examples include the atmospheres of white dwarfs; accretion phenomena in young stars, cataclysmic variables and active ga…
Constraining the AGN Contribution in a Multiwavelength Study of Seyfert Galaxies
M. Meléndez, S. B. Kraemer, H. R. Schmitt +4
We have studied the relationship between the high- and low-ionization [O IV] lambda 25.89 micron, [Ne III] lambda 15.56 micron and [Ne II] lambda 12.81 micron emission lines with t…
Discovery of CH and OH in the -513 km s-1 Ejecta of Eta Carinae
E. Verner, F. Bruhweiler, K. E. Nielsen +3
The very massive star, Eta Carinae, is enshrouded in an unusual complex of stellar ejecta, which is highly depleted in C and O, and enriched in He and N. This circumstellar gas giv…
System Parameters of the Transiting Extrasolar Planet HD 209458b
Robert A. Wittenmyer, William F. Welsh, Jerome A. Orosz +10
We derive improved system parameters for the HD 209458 system using a model that simultaneously fits both photometric transit and radial velocity observations. The photometry consi…
The Binarity of Eta Carinae Revealed from Photoionization Modeling of the Spectral Variability of the Weigelt Blobs B and D
E. Verner, F. Bruhweiler, T. Gull
We focus on two Hubble Space Telescope/Space Telescope Imaging Spectrograph (HST/STIS) spectra of the Weigelt Blobs B&D, extending from 1640 to 10400A; one recorded during the 1998…
