Report

System parameters, transit times and secondary eclipse constraints of the exoplanet systems HAT-P-4, TrES-2, TrES-3 and WASP-3 from the NASA EPOXI Mission of Opportunity

Autor: Christiansen, Jessie L., Ballard, Sarah, Charbonneau, David, Deming, Drake, Holman, Matthew J., Madhusudhan, Nikku, Seager, Sara, Wellnitz, Dennis D., Barry, Richard K., Livengood, Timothy A., Hewagama, Tilak, Hampton, Don L., Lisse, Carey M., A'Hearn, Michael F.

As part of the NASA EPOXI Mission of Opportunity, we observed seven known transiting extrasolar planet systems in order to construct time series photometry of extremely high phase coverage and precision. Here we present the results for four "hot-Jupi

Report

The NASA EPOXI mission of opportunity to gather ultraprecise photometry of known transiting exoplanets

Autor: Christiansen, Jessie L., Charbonneau, David, A'Hearn, Michael F., Deming, Drake, Holman, Matthew J., Ballard, Sarah, Weldrake, David T. F., Barry, Richard K., Kuchner, Marc J., Livengood, Timothy A., Pedelty, Jeffrey, Schultz, Alfred, Hewagama, Tilak, Sunshine, Jessica M., Wellnitz, Dennis D., Hampton, Don L., Lisse, Carey M., Seager, Sara, Veverka, Joseph F.

The NASA Discovery mission EPOXI, utilizing the Deep Impact flyby spacecraft, comprises two phases: EPOCh (Extrasolar Planet Observation and Characterization) and DIXI (Deep Impact eXtended Investigation). With EPOCh, we use the 30-cm high resolution

NIR Meinel 0-0 band aurora during moderate substorms

Autor: Zhou, Xiaoyan, Hampton, Don

Publikováno v: XXVIII General Assembly of the International Union of Geodesy and Geophysics (IUGG)

The Meinel band (at 1103 to 1134 nm) is solely attributed to the electron bombardment and, therefore, manifests electron precipitations and accelerations driven by the MIT coupling. In preparation for the BALBOA balloon mission of imaging aurora in s

Observations of ion upflow and 630.0 nm emission during pulsating aurora

Autor: Godbole, Niharika H., Lessard, Marc R., Kenward, David R., Fritz, Bruce A., Varney, Roger. H., Michell, Robert G., Hampton, Don

Publikováno v: Frontiers in Physics. 10

In this study, we report observations made by filtered (557.7 and 630.0 nm) All-Sky Imagers located at Poker Flat, Alaska alongside Poker Flat Incoherent Scatter Radar data for an event observed on 5 February 2017. Together, the data indicate ion upf
