On the motion and physical properties of magnetic bright points in the solar photosphere
High-resolution observations of the solar photosphere have revealed the existence of structures composed oftiny Magnetic Bright Points, or MBPs. Such small-scale structures are associated with regions of strongmagnetic field on the order of kilogauss (kG). Various studies have investigated some of t...

Tales estructuras a pequeñaescala están asociadas con regiones de campo magnético fuerte del orden de kilogauss (kG). Diversasinvestigaciones han estudiado algunas de las propiedades físicas de los MBPs gracias a observaciones de altaresolución que permiten en la actualidad definir detalles y evolución de tales estructuras. El presente estudiohace un análisis de algunos de estos parámetros dinámicos a través del uso de series de tiempo de imágenesde la fotosfera solar adquiridas con el telescopio solar terrestre de alta resolución, HiFI/GREGOR en labanda G (4308 Å) y el telescopio espacial Hinode. Se realiza el seguimiento de los MBPs para determinar susmovimientos propios. Adicionalmente se obtienen curvas de luz que evidencian su variación en intensidad yse analiza cómo es el comportamiento del tamaño y de la trayectoria a lo largo de su tiempo de vida. Losresultados establecen que las medidas de los parámetros dinámicos de los MBPs están influenciadas porel instrumento utilizado, ya que con el cambio de la resolución espacial y temporal se obtienen resultadosdiferentes.application/pdfspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ciencia_en_desarrollo/article/view/15241/12661Ciencia En Desarrollo; Vol. 1 No. 2E (2022): Núm. 2E (2022): Número Especial: VII Congreso de Astronomía y Astrofísica 2022; 37-45Ciencia en Desarrollo; Vol. 1 Núm. 2E (2022): Núm. 2E (2022): Número Especial: VII Congreso de Astronomía y Astrofísica 2022; 37-452462-76580121-7488fotosfera - Sol: evolución - métodos: observacional.Sun: photosphere, evolution, observational methods.On the motion and physical properties of magnetic bright points in the solar photosphereSobre el movimiento y propiedades físicas de puntos magnéticos brillantes en la fotosfera solarinfo:eu-repo/semantics/articlehttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1http://purl.org/coar/access_right/c_abf2Berrios Saavedra, Yeimy GerardineUtz, Dominik Vargas, Santiago 001/15378oai:repositorio.uptc.edu.co:001/153782025-07-18 10:56:46.211metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
