Structures seen on the solar photosphere in the H-alpha emission line of hydrogen Filaments are most likely to occur in active regions and so are most common near solar maximum
Thin longitudinal "threads" of glass' polyester' nylon' or other high-strength materials
A structure in the corona consisting of cool plasma supported by magnetic fields Filaments are dark structures when seen against the bright solar disk, but appear bright when seen over the solar limb, Filaments seen over the limb are also known as prominences more!
The stem or stalk upon which the anther sits; together, the filament and anther make up the stamen, which is the male reproductive system (in the flower) of a plant
A metallic coil inside the glass tube of a bulb with enough resistance that when an adequate electrical current flows through the coil, it glows and produces the light output
A strand of cool gas suspended over the photosphere by magnetic fields, which appears dark as seen against the disk of the Sun; a filament on the limb of the Sun seen in emission against the dark sky is called a prominence
1)fiber characterized by extreme length 2)the resistance wire through which filament current is sent in a therm ionic tube to produce the heat required for electron emission
A mass of gas suspended over the chromosphere by magnetic fields and seen as dark ribbons threaded over the solar disk A filament on the limb of the Sun seen in emission against the dark sky is called a prominence Filaments occur directly over magnetic-polarity inversion lines, unless they are active
two meanings: for a flower, it is referring to the stalk of a stamen which supports the anther (male part of the flower; filament also means a thread-like process (like the thin wire coiled in a light bulb)
A mass of gas suspended over the photosphere by magnetic fields and seen as dark lines threaded over the solar disk A filament on the limb of the Sun seen in emission against the dark sky is called a prominence
1) Fiber characterized by extreme length 2) The resistance wire through which filament current is sent in a thermionic tube to produce the heat required for electron emission
{i} fiber, thin threadlike object; thin wire; thin conductor which heats up and emits light in response to an electrical current (in an incandescent light bulb); heating element of a vacuum tube
the heating element in an electron tube, also called the "heater" The filament heats the cathode to a very high temperature, which "boils off" electrons, which are then collected by the plate The filament can be seen as the glowing element through the holes in the plate of most tubes
A strand of (relatively) cool gas suspended over the Sun (or star) by magnetic fields, which appears dark against the disc of the Sun A filament on the limb of the Sun seen in emission against the dark sky is called a solar prominence
filum = [Latin] thread Filaments are prominences seen against the solar disk Because the solar disk is brighter than the filaments, the filaments appear dark Filaments can be seen only in the centers of strong spectral lines, such as Ca K or H alpha The full-disk H-alpha image shows several filaments
a thin wire (usually tungsten) that is heated white hot by the passage of an electric current a threadlike anatomical structure or chainlike series of cells the stalk of a stamen
