On rotation of solar filaments [PDF]

open access: yesProceedings of the International Astronomical Union, 2006
The study of the differential rotation law is an important issue in solar physics. Earlier studies of filaments found formulae for their differential rotation at stable existence stage. This paper relies on Big Bear Solar Observatory H-alpha filtergrams to estimate angular velocities of quiescent filaments at different stages of existence.

The effect of colour on the thermal performance of building integrated solar collectors [PDF]

open access: yes, 2010
The use of solar collectors with coloured absorbers for water heating is an area of particular interest when considering their integration with buildings.

Performance of a building integrated photovoltaic/thermal (BIPVT) solar collector [PDF]

open access: yes, 2009
The idea of combining photovoltaic and solar thermal collectors (PVT collectors) to provide electrical and heat energy is an area that has, until recently, received only limited attention.

Latitude migration of solar filaments [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2010
The Carte Synoptique catalogue of solar filaments from March 1919 to December 1989, corresponding to complete cycles 16 to 21 is utilized to show latitudinal migration of filaments at low latitudes (less than 50 deg), and the latitudinal drift of solar filaments in each hemisphere in each cycle of the time interval is compared with the corresponding ...

Commission 10: Solar Activity [PDF]

open access: yes, 2007
Commission 10 aims at the study of various forms of solar activity, including networks, plages, pores, spots, fibrils, surges, jets, filaments/prominences, coronal loops, flares, coronal mass ejections (CMEs), solar cycle, microflares, nanoflares ...

SYMPATHETIC SOLAR FILAMENT ERUPTIONS [PDF]

open access: yesThe Astrophysical Journal Letters, 2016
ABSTRACT The 2015 March 15 coronal mass ejection as one of the two that together drove the largest geomagnetic storm of solar cycle 24 so far was associated with sympathetic filament eruptions. We investigate the relations between the different filaments involved in the eruption.

Characterization of cells of amniotic fluids by immunological identification of intermediate-sized filaments: Presence of cells of different tissue origin [PDF]

open access: yes, 1981
Antibodies against intermediate-sized filaments, of the prekeratin or vimentin type, were used to investigate the presence of these filaments by indirect immunofluorescence microscopy in cultured and non-cultured amniotic fluid cells, in frozen sections ...

Network Jets as the Driver of Counter-streaming Flows in a Solar Filament/Filament Channel [PDF]

open access: yesThe Astrophysical Journal Letters, 2020
Abstract Counter-streaming flows in a small (100″ long) solar filament/filament channel are directly observed in high-resolution Solar Dynamics Observatory (SDO)/Atmospheric Imaging Assembly (AIA) extreme-ultraviolet (EUV) images of a region of enhanced magnetic network.
