Energy Evolution from the Chromosphere to the Heliosphere in the 2021 October 28 Solar Eruption
Katharine K. Reeves, Daniel B. Seaton, Cynthia Cattell +20
We perform a detailed study of the energetics for a well-observed solar eruption and flare that occurred on 28 October 2021. This event included a GOES class X1.0 flare, a global E…
Strong Prevalence of Hammerhead Velocity Distributions Close to the Heliospheric Current Sheet
Srijan Bharati Das, Jaye L. Verniero, Samuel T. Badman +13
The solar wind undergoes non-adiabatic heating as it travels away from the Sun. The velocity phase space distribution of non-equilibrium ions in the solar wind indicate a source of…
Tracing a Multi-Temperature Quiescent Prominence's Thermodynamic Evolution from Sun to Earth
Callie A. GarcÃa, Yeimy J. Rivera, Samuel T. Badman +5
Solar prominences are cool, dense stable structures routinely observed in the corona. Prominences are often ejected from the Sun via coronal mass ejections (CMEs). However, they ar…
Observation and modeling of a geo-effective event observed on 2011 May 28 from the solar surface to 1au
Nishu Karna, Tatiana Niembro
In this study, we present a comprehensive observational and modeling study of a geo-effective event with D_ST index of -80 nT observed on 2011 May 28 when a coronal hole was border…
Multi-spacecraft Measurements of the Evolving Geometry of the Solar Alfvén Surface Over Half a Solar Cycle
Samuel T. Badman, Michael L. Stevens, Stuart D. Bale +18
The geometry of a star's Alfvén surface determines stellar angular momentum loss, separates a causally distinct 'corona' and stellar wind, and potentially affects exoplanetary hab…
Helium Abundance Periods Observed by the Solar Probe Cup on Parker Solar Probe: Encounters 1-14
Madisen Johnson, Yeimy J. Rivera, Tatiana Niembro +7
Parker Solar Probe is a mission designed to explore properties of the solar wind closer than ever before. Detailed particle observations from the Solar Probe Cup (SPC) have primari…
