Where are plages located on the Sun?
chromosphere
A plage (/pleɪdʒ/) is a bright region in the chromosphere of the Sun, typically found in and around active regions. The term plage is poetically taken from the French word for “beach”. Plage map closely to the bright spots known as faculae in the photosphere below, but the latter have much smaller spatial scales.
Where are plages found?
Prominences and plages are structures that occur above the photosphere of the Sun. Plages are bright cloud-like features found around sunspots that represent regions of higher temperature and density within the chromosphere.
How are plages related to sunspots?
Plages are the chromospheric features that appear as bright patches on the solar disk when seen through Ca ii K line (3933.67 Å) images, whereas sunspots are the dark photospheric features prominently visible in white-light images.
What causes plages in the Sun?
Plage, the French word for beach, are bright patches surrounding sunspots that are best seen in H-alpha. Plage are also associated with concentrations of magnetic fields and form a part of the network of bright emissions that characterize the chromosphere.
Is there a connection between plages and sunspots quizlet?
Is there a connection between plages and sunspots? Yes, the magnetic fields that result in sunspots in the photosphere compress the gases above the photosphere, and this pressure creates plages in the chromosphere.
What is immediately above the Sun’s photosphere?
The lower section of the Sun’s atmosphere, the chromosphere, lies above the photosphere.
Where are solar flares located on the Sun?
Flares occur in active regions often around sunspots, where intense magnetic fields penetrate the photosphere to link the corona to the solar interior. Flares are powered by the sudden (timescales of minutes to tens of minutes) release of magnetic energy stored in the corona.
How would sunspots appear if you could magically remove them from the Sun?
How would sunspots appear if you could magically remove them from the Sun? They would shine bright orange in color, like Arcturus. While observing the Sun, you note a large number of sunspots.
What is corona in the Sun?
corona, outermost region of the Sun’s atmosphere, consisting of plasma (hot ionized gas). It has a temperature of approximately two million kelvins and an extremely low density. The corona continually varies in size and shape as it is affected by the Sun’s magnetic field.
What is the uppermost layer of the Sun?
The uppermost is the Convective Zone . It extends downwards from the bottom of the photosphere to a depth of about 15% of the radius of the Sun. Here the energy is mainly transported upwards by (convection) streams of gas. The Radiative Zone is below the convection zone and extends downwards to the core.
What is chromosphere of the Sun?
chromosphere, lowest layer of the Sun’s atmosphere, several thousand kilometres thick, located above the bright photosphere and below the extremely tenuous corona.
What are the plages of the Sun?
Figure 1. Plages on the Sun: This image of the Sun was taken with a filter that transmits only the light of the spectral line produced by singly ionized calcium. The bright cloud-like regions are the plages. (credit: modification of work by NASA) As we saw, emission lines of hydrogen and calcium are produced in the hot gases of the chromosphere.
What are solar Plages in geology?
Solar Plages. Plages are bright areas of solar activity found around sunspots that represent regions of higher temperature and density within the chromosphere (The word “plage” derives from the French for “beach”).
What are Plages and how are they visible?
Plages are particularly visible when photographed through filters passing the spectral light of hydrogen or calcium (see the right panel). In the adjacent image from Big Bear Solar Observatory, the bright cloud-like feature near the sunspot is a plage.
What are Plages in the chromosphere?
Pictures taken through these special filters show bright “clouds” in the chromosphere around sunspots; these bright regions are known as plages (Figure 1). These are regions within the chromosphere that have higher temperature and density than their surroundings.
