Shock wave driven by CME evidenced by metric type II burst and EUV wave
Selhorst, C. L.; Cunha-Silva, R. D.; Fernandes, F. C. R.
Solar type II radio bursts are produced by plasma oscillations in the solar corona as a result of shock waves. The relationship between type II bursts and coronal shocks is well evidenced by observations since the 1960s. However, the drivers of the shocks associated with type II events at metric wavelengths remain as a controversial issue among so…
Interpreting Ulysses data using inverse scattering theory: Oblique Alfvén waves
Wheeler, Harry R.; Reynolds, M. A.; Hamilton, R. L.
Solitary wave structures observed by the Ulysses spacecraft in the solar wind were analyzed using both inverse scattering theory and direct numerical integration of the derivative nonlinear Schrödinger (DNLS) equation. Several of these structures were found to be consistent with soliton solutions of the DNLS equation. Such solitary structures have…
Relating field-aligned beams to inverted-V structures and visible auroras
Dandouras, I.; Rème, H.; Parks, G. K. +5 more
The ion composition experiment on Cluster measures 3-D distributions in one spin of the spacecraft (4 s). These distributions often measure field-aligned ion beams (H+, He+ and O+) accelerated out of the ionosphere. The standard model of these beams relies on a quasi-static U-shaped potential model. The beams conta…
Dust processing in the Carina nebula region
Onaka, Takashi; Okada, Yoko; Mori, Tamami I.
Dust processing in the Carina nebula is investigated based on mid- to far-infrared spectroscopy with Infrared Space Observatory (ISO). Mapping observations over a central 40‧ ×20‧ area of the nebula with PHT-S, SWS, and LWS onboard ISO not only reveal spectroscopically that the mid-infrared unidentified infrared (UIR) bands a…

Ultraviolet spectroscopy of V Sagittae in high, intermediate and low states from HST and IUE satellites
Sanad, M. R.
We present the first phase resolved ultraviolet spectroscopic study of V Sge in high, intermediate and low states observed with the Hubble Space Telescope High Resolution Spectrograph (HST HRS) and International Ultraviolet Explorer (IUE) during the period 1978–1996 to diagnose the ultraviolet fluxes of C IV 1550 Å and He II 1640 Å emission lines …
Structural and morphological properties of ultraluminous infrared galaxies at 1<z<3
Fang, Guanwen; Kong, Xu; Chen, Yang +1 more
Using the Hubble Space Telescope (HST)/Wide Field Camera 3 (WFC3) near-infrared high-resolution imaging from the 3D-HST survey, we analyze the morphology and structure of 502 ultraluminous infrared galaxies (ULIRGs; LIR>1012L⊙) at 1<z< 3. Their rest-frame optical morphologies show that high-redshift ULIRGs…
