Simulated larvae dispersion of the invasive sun-coral (Tubastrea spp.) along Rio de Janeiro's coast: The role of submesoscale filaments on offshore transport and connectivity. [PDF]
PLoS OneThe spread of invasive species in marine ecosystems is a growing global concern, particularly in regions with high economic and ecological importance. Sun corals (Tubastraea spp.) are native scleractinians from the Pacific Ocean that have spread along most of the Brazilian coast. This invasive species initially established populations in Rio de Janeiro

Evolution of photospheric flows under an erupting filament in the quiet-Sun region [PDF]
Astronomy & Astrophysics, 2020 Context. We studied the dynamics of the solar atmosphere in the region of a large quiet-Sun filament, which erupted on 21 October 2010. The filament eruption started at its northern end and disappeared from the Hα line-core filtergrams line within a few hours.

Mean Field Model for the Formation of Filament Channels on the Sun [PDF]
The Astrophysical Journal, 2000 The coronal magnetic field is subject to random footpoint motions that cause small-scale twisting and braiding of field lines. We present a mean field theory describing the effects of such small-scale twists on the large-scale coronal field. This theory assumes that the coronal field is force free, with electric currents flowing parallel or ...

The Formation of a Small-Scale Filament After Flux Emergence on the Quiet Sun [PDF]
Solar Physics, 2018 We present observations of the formation process of a small-scale filament on the quiet Sun during 5-6 February 2016 and investigate its formation cause. Initially, a small dipole emerged and its associated arch filament system was found to reconnect with overlying coronal fields accompanied by numerous EUV bright points.

The Astrophysical Journal Letters, 2023 Abstract Cylindrical molecular filaments are observed to be the main sites of Sunlike star formation, while massive stars form in dense hubs at the junction of multiple filaments. The role of hub–filament configurations has not been discussed yet in relation to the birth environment of the solar system and to infer the origin of isotopic

The Astrophysical Journal, 2023 Abstract Partial filament eruptions have often been observed; however, the physical mechanisms that lead to filament splitting are not yet fully understood. In this study, we present a unique event of a partial filament eruption that undergoes two distinct splitting processes.

MASS COMPOSITION IN PRE-ERUPTION QUIET SUN FILAMENTS
The Astrophysical Journal, 2009 Filament eruptions are extremely important phenomena due to their association with coronal mass ejections and their effects on space weather. Little is known about the filament mass and composition in the eruption process, since most of the related research has concentrated on the evolution and disruption of the magnetic field.

Counter-streaming flows in a giant quiet-Sun filament observed in the extreme ultraviolet [PDF]
Astronomy & Astrophysics, 2018 Aim. The giant solar filament was visible on the solar surface from 2011 November 8–23. Multiwavelength data from the Solar Dynamics Observatory (SDO) were used to examine counter-streaming flows within the spine of the filament.Methods. We use data from two SDO instruments, the Atmospheric Imaging Assembly (AIA) and the Helioseismic and Magnetic ...
