X-ray Orbital Modulations in Intermediate Polars [PDF]

, 2005
We present an analysis of 30 archival ASCA and RXTE X-ray observations of 16 intermediate polars to investigate the nature of their orbital modulation.

Ionospheric Disturbances During the 4 December 2015, Mt. Etna Eruption

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract This study presents the detection and characterization of co‐volcanic ionospheric disturbances (CVIDs) associated with Mt. Etna's large‐scale lava fountain (Italy). Leveraging a dense and proximal GNSS network, we identify local Total Electron Content (TEC) perturbations extending up to ∼ ${\sim} $200 km south/southwest of the vent.

Daytime Thermospheric Wind Transients and Circulation in May 2021

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Changes in the thermospheric wind originating in storm‐time transients in high‐latitude Joule heating and ion circulation are effective in modifying conditions throughout Earth's upper atmosphere and ionosphere. Among the effects these drivers can produce are large‐scale gravity waves (GWs), characterized by significant wind transients that ...

Occurrence Rates and Variability of Whistler‐Mode Waves in the Plasma Trough

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Numerical models of energetic electron behavior in the outer radiation belt require descriptions of the wave‐particle interactions across the inner magnetosphere. Quasilinear diffusion coefficients describe gyro‐resonant wave‐particle interactions over large time‐ and length‐scales but these must be constrained by observations to construct ...

Astrometric positions for 18 irregular satellites of giant planets from 23 years of observations

, 2015
The irregular satellites of the giant planets are believed to have been captured during the evolution of the solar system. Knowing their physical parameters, such as size, density, and albedo is important for constraining where they came from and how ...

Long-Term Optical Observations Of Two Lmxbs: Uw Crb (=Ms 1603+260) And V1408 Aql (=4U 1957+115) [PDF]

, 2012
We present new optical photometry of two low-mass X-ray binary stars, UW CrB (MS 1603+260) and V1408 Aql (4U 1957+115). UW CrB is an eclipsing binary and we refine its eclipse ephemeris and measure an upper limit to the rate of change of its orbital ...

Automated Bow Shock Identification and Multi‐Spacecraft Timing Using Magnetospheric Multiscale (MMS) Observations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Utilizing 8 years of dayside Magnetospheric Multiscale (MMS) mission plasma region identifications, we present an automatically identified and manually verified data set of 2,594 bow shock crossings in MMS burst‐mode. For each bow shock crossing, we identify the bow shock ramp in each MMS probe using two automated methods and apply multi ...

A Search for Hierarchical Triples using Kepler Eclipse Timing

, 2012
We present the first results of a Kepler survey of 41 eclipsing binaries that we undertook to search for third star companions. Such tertiaries will periodically alter the eclipse timings through light travel time and dynamical effects.
