Planetesimals to terrestrial planets: Collisional evolution amidst a dissipating gas disk [PDF]

Icarus (New York, N.Y. 1962), 2019
We present numerical simulations of terrestrial planet formation that examine the growth continuously from planetesimals to planets in the inner Solar System.

Solar Terrestrial Relations Observatory (STEREO) Observations of Stream Interaction Regions in 2007 – 2016: Relationship with Heliospheric Current Sheets, Solar Cycle Variations, and Dual Observations [PDF]

Solar Physics, 2019
We have conducted a survey of 575 slow-to-fast stream interaction regions (SIRs) using Solar Terrestrial Relations Observatory (STEREO) A and B data, analyzing their properties while extending a Level-3 data product through 2016. Among 518 pristine SIRs, 54% are associated with heliospheric current sheet (HCS) crossings, and 34% are without any HCS ...

Kinetic and Hydrodynamic Models of the Solar Wind and Polar Wind: A Focus Group of the Solar‐Terrestrial Interactions From Microscale to Global Models (STIMM‐2) Workshop; Sinaia, Romania, 13 and 15 June 2007 [PDF]

Eos, Transactions American Geophysical Union, 2008
Following the publication of the first hydrodynamic models of the “solar wind” (supersonic neutral outstream of solar charged particles) in 1958, and the “solar breeze” (the evaporation of solar particles with a subsonic mean velocity) in 1960, scientists for decades have debated about which description most accurately models the acceleration of ...

Prediction Capability of Geomagnetic Events from Solar Wind Data Using Neural Networks

The Astrophysical Journal, 2023
Multiple neural network architectures, with different structural composition and complexity, are implemented in this study with the aim of providing multi-hour-ahead warnings of severe geomagnetic disturbances, based on in situ measurements of the solar ...

Evaluating aerosol direct radiative effects on global terrestrial ecosystem carbon dynamics from 2003 to 2010 [PDF]

Tellus: Series B, Chemical and Physical Meteorology, 2014
An integrated terrestrial ecosystem model and an atmospheric radiative transfer module are developed and applied to evaluate aerosol direct radiative effects on carbon dynamics of global terrestrial ecosystems during 2003–2010.

Formation of a Magnetic Cloud from the Merging of Two Successive Coronal Mass Ejections

The Astrophysical Journal Letters
On 2022 March 28 two successive coronal mass ejections (CMEs) were observed by multiple spacecraft and resulted in a magnetic cloud (MC) at 1 au. We investigate the propagation and interaction properties of the two CMEs correlated with the MC using ...

Solar Radio Spectro-polarimeter (50–500 MHz). I. Design, Development, and Characterization of a Cross-polarized, Log-periodic Dipole Antenna

The Astrophysical Journal, 2023
The Zeeman effect has been routinely used to image and quantify the solar photospheric magnetic field (B). Such a direct measuring technique is not yet available for the corona (Lin et al. 2004). Since almost all transient nonthermal radio emissions from

Unveiling the Interplanetary Solar Radio Bursts of the 2024 Mother’s Day Solar Storm

Astrophysical Journal Letters
We report on a comprehensive study of interplanetary type III radio bursts linked to X-class solar flares from NOAA active region 13664, which instigated the intense 2024 Mother’s Day solar storm, marked by a geomagnetic storm of −412 nT, the strongest ...

Statistical Properties of Whistler-mode Waves in the Dayside Terrestrial Space: MMS Observations

The Astrophysical Journal
Whistler-mode waves have been extensively observed and investigated in terrestrial space. In this study, we present the dynamic response of whistler-mode waves to different solar wind conditions in the dayside terrestrial space based on Magnetospheric ...
