PPS01-P08 Japan Geoscience Union Meeting 2016
PPS01-P08 Japan Geoscience Union Meeting 2016 Statistical study of the response of Jovian EUV aurora to the solar wind from Hisaki observations Hajime Kita1, Tomoki Kimura2, Chihiro Tao3, *Fuminori Tsuchiya1, Hiroaki Misawa1, Takeshi Sakanoi1, Yasumasa Kasaba1, Go Murakami4, Kazuo Yoshioka5, Atsushi Yamazaki4, Ichiro Yoshikawa6 1.Graduate School of Science, Tohoku University, 2.Nishina-Center for Accelerator Based Science, RIKEN, 3.National Institute of Information and Communications Technology, 4.Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency, 5.Department of Earth and Planetary Science, Graduate School of Science, University of Tokyo, 6.Department of Complexity Science and Engineering, University of Tokyo In order to reveal the solar wind response of Jovian extreme ultraviolet (EUV) auroral activity, we made a statistical analysis of Jovian EUV aurora obtained from long term Hisaki observation. The EUV emission from hydrogen molecule is excited by collision with high energy electron. The main oval is one of the components of Jovian EUV aurora where the auroral particle precipitations are caused by the rotationally driven field-aligned current system. It is theoretically expected that angular velocity of magnetospheric plasma increases when the Jovian magnetosphere is compressed by enhanced solar wind pressure, which decreases the field-aligned current. Regarding this scenario, increase of the solar wind dynamic pressure is expected to be anti-correlated with the intensity of the EUV aurora. A previous observation such as that by International Ultraviolet Explorer (IUE) or Hubble Space Telescope (HST) showed the time variability of the EUV aurora, while their data still limited in continuity over solar wind variation with good time resolution. -
2019 Astrophysics Senior Review Senior Review Subcommittee Report
2019 Astrophysics Senior Review Senior Review Subcommittee Report 2019 Astrophysics Senior Review - Senior Review Subcommittee Report June 4-5, 2019 SUBCOMMITTEE MEMBERS Dr. Alison Coil, University of California San Diego Dr. Megan Donahue, Michigan State University Dr. Jonathan Fortney, University of California Santa Cruz Ms. Maura Fujieh, NASA Ames Research Center Dr. Roberta Humphreys, University of Minnesota Dr. Mark McConnell, University of New Hampshire / Southwest Research Institute Dr. John O’Meara, Keck Observatory Dr. Rebecca Oppenheimer, American Museum of Natural History Dr. Alexandra Pope, University of Massachusetts Amherst Dr. Wilton Sanders, NASA/University of Wisconsin-Madison, retired Dr. David Weinberg, The Ohio State University - Chair 1 EXECUTIVE SUMMARY The eight missions evaluated by the 2019 Astrophysics Senior Review constitute a portfolio of extraordinary scientific power, on topics that range from the atmospheres of planets around nearby stars to the nature of the dark energy that drives the accelerating expansion of the cosmos. The missions themselves range from the venerable Great Observatories Hubble and Chandra to the newest Explorer missions NICER and TESS. All of these missions are operating at a high level technically and scientifically, and all have sought ways to make their operations cost-efficient and their data valuable to a broad community. The complementary nature of these missions makes the overall capability of the portfolio more than the sum of its parts, and many of the most exciting developments in contemporary astrophysics draw on observations from several of these observatories simultaneously. The Senior Review Subcommittee recommends that NASA continue to operate and support all eight of these missions. -

New Year's Address January 4, 2017 Saku Tsuneta, Director General
New Year’s Address January 4, 2017 Saku Tsuneta, Director General, Institute of Space and Astronautical Science Happy New Year, everyone. I hope most of the staff members of this institute have enjoyed their New Year’s vacation although it was not so long, and I am especially thankful to those people working hard in the critical phase of the Arase mission and those preparing for the launch of SS-520-4, including the support members of manufacturers. Successful launch of Arase and Epsilon launch vehicle In late December, we successfully launched ARASE, or the Exploration of energization and Radiation in Geospace (ERG) satellite, using the Epsilon-2 Launch Vehicle. It was a truly wonderful launch experience for all of us. The Epsilon launch vehicle was developed and launched under the management of the Space Technology Directorate I of JAXA. Hence, the Project Manager, Dr. Yasuhiro Morita led the overall program management and Mr. Takayuki Imoto acted as the sub-manager to command the frontline. I would like to say special thanks to both leaders and the project members of JAXA and ISAS who have been involved in this program. The second-stage rocket of Epsilon-2 has been newly developed to give it higher performance and a lower cost, and the launch capability has increased by about 30 percent from that of Epsilon-1. These newly developed technologies will be used in the solid rocket booster, SRB-3, of the H3 launch vehicle. Then, the SRB-3 booster will be used as the first-stage rocket of Epsilon launch vehicles. -

Atmosphere from Cassini Grand Finale system planets, making them crucial analogs for exoplanets, which cannot be Planetary Laboratory Esposito *presenting author Stellar Occultations explored in the same level of detail. The Cassini Ultraviolet Imaging Spectrograph (UVIS) observed UV-bright O, A, and B stars as they passed behind the limb of Saturn, allowing for profiles of density and temperature in the upper atmosphere. By analyzing UVIS stellar occultations from 2016 and 2017, including Grand Finale data, we created the first 2D maps of Saturn’s density and temperature in thermosphere, from which we infer horizontal winds. Our results have implications the "energy-crisis" of the outer planet thermospheres, which are hotter than can be explained by solar heating alone. Our results indicate that Joule heating at auroral latitudes is important and that this energy can be transported to lower latitudes, adding to growing evidence that this mechanism contributes significantly to the observed temperatures. Chenliang Huang Tommi Koskinen A hydrodynamic study of radiative cooling The heating by photo-ionization in the thermosphere of short-period University of Arizona and escape of metal species in hot Jupiter exoplanets can drive hydrodynamic escape, which is key to understanding the atmospheres evolution of the planet atmosphere and explaining the atmospheric measurements. Besides powering the atmosphere escape, the energy deposited by EUV photons from the host star can also be radiated away through collisional excited atomic spectral lines, leading the mass loss rate to fall significantly below the energy limit. -

268 JOURNAL OF ATMOSPHERIC AND OCEANIC TECHNOLOGY VOLUME 23 Ocean Wave Directional Spectra Estimation from an HF Ocean Radar with a Single Antenna Array: Methodology YUKIHARU HISAKI Department of Physics and Earth Sciences, University of the Ryukyus, Nishihara-cho, Nakagami-gun, Okinawa, Japan (Manuscript received 27 May 2004, in final form 10 April 2005) ABSTRACT A method to estimate ocean wave directional spectra using a high-frequency (HF) ocean radar was developed. The governing equations of wave spectra are integral equations of first- and second-order radar cross sections, the wave energy balance equation, and the continuity equation of surface winds. The parameterization of the source function is the same as that in WAM. Furthermore, the method uses the constraints that wave spectral values are smooth in both wave frequency and direction and that the propa- gation terms are small. The unknowns to be estimated are surface wind vectors at radial grids whose centers are the radar position, and wave spectral values at radial and wave frequency–direction grids. The governing equations are discretized in the radial and wave frequency–direction grids and are converted into a non- linear minimization problem. Identical twin experiments showed that the present method can estimate wave spectra and dynamically extrapolate wave spectra, even in an inhomogeneous wave field. 1. Introduction of HF ocean radars in measuring waves. One problem is that a wide area is necessary to deploy the HF radar’s A directional spectrum is the most common way of antenna. The coastal radar (CODAR)-type compact describing the properties of ocean surface waves in en- antenna systems (e.g., Lipa and Barrick 1986) require ergy (amplitude), frequency, and direction of propaga- spatial homogeneity in the wave field over a wide tion. -

Murakami · M. Kagitani · Y. Kasaba · I. Yoshikawa · N. Terada · T. Kimura · S. Sakai · K. Nakaya · S. Fukuda · S. Sawai Received: 25 April 2014 / Accepted: 27 September 2014 / Published online: 22 October 2014 © The Author(s) 2014. This article is published with open access at Springerlink.com Abstract HISAKI (SPRINT-A) satellite is an earth-orbiting Extreme UltraViolet (EUV) spectroscopic mission and launched on 14 Sep. 2013 by the launch vehicle Epsilon-1. Ex- treme ultraviolet spectroscope (EXCEED) onboard the satellite will investigate plasma dy- namics in Jupiter’s inner magnetosphere and atmospheric escape from Venus and Mars. EUV spectroscopy is useful to measure electron density and temperature and ion composi- tion in plasma environment. EXCEED also has an advantage to measure spatial distribution of plasmas around the planets. To measure radial plasma distribution in the Jovian inner magnetosphere and plasma emissions from ionosphere, exosphere and tail separately (for Venus and Mars), the pointing accuracy of the spectroscope should be smaller than spa- tial structures of interest (20 arc-seconds). For satellites in the low earth orbit (LEO), the pointing displacement is generally caused by change of alignment between the satellite bus module and the telescope due to the changing thermal inputs from the Sun and Earth. The HISAKI satellite is designed to compensate the displacement by tracking the target with using a Field-Of-View (FOV) guiding camera.
