A plage / p l eɪ dʒ / is a bright region in the Sun's chromosphere, typically found in and around active regions. Historically, they have been referred to as bright flocculi, in contrast to dark flocculi, and as chromospheric faculae, in contrast to photospheric faculae. [1]

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.

Sep 11, 2023 · João’s research centers on solar plages, which are bright patches on the Sun’s surface that correspond to magnetic activity. Magnetic fields play a pivotal role in understanding the Sun’s atmospheric phenomena, though their precise mechanisms remain elusive.

Sep 7, 2023 · Here, we utilize high-sensitivity, spectropolarimetric data obtained by the 4 meter Daniel K. Inouye Solar Telescope to investigate the dynamic environment and magnetic field stratification of an extended, decaying plage region.

Feb 7, 2024 · We use data obtained with the high-resolution Visible Broadband Imager (VBI) equipped with an H β filter and the Visible Spectro-Polarimeter (ViSP) at the Daniel K. Inouye Solar Telescope to investigate the fine-scale structure of the plage chromosphere.

We compare the properties of kG magnetic structures in the solar network and in active region plage at high spatial resolution. Methods. Our analysis used six SP scans of the solar disc centre aboard Hinode SOT and inverted the obtained spectra of the photo-spheric 6302Å line pair using the 2D SPINOR code. Results.

Apr 1, 2024 · We investigated the fine-scale structure of the plage chromosphere by analyzing broadband imaging and full Stokes spectropolarimetric observations in the Hβ, Ca ii 8542 Å, and Fe i 6301/6302 Å lines obtained with the largest solar optical telescope, DKIST.

Aug 21, 2023 · Here, we utilize high-sensitivity, spectropolarimetric data obtained by the four-meter Daniel K. Inouye Solar Telescope (DKIST) to investigate the dynamic environment and magnetic field stratification of an extended, decaying plage region.

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").

A plage is a bright region in the Sun's chromosphere, typically found in and around active regions. Historically, they have been referred to as bright flocculi , in contrast to dark flocculi, and as chromospheric faculae , in contrast to photospheric faculae.
