Study of Doppler velocities and their relationship with Magnetic field oscillations in the penumbra of Sunspots
Local oscillations of the Doppler Velocities in the penumbra of the sunspot AR12186 were studied. For thispurpose, the images were aligned using the Enhanced Correlation Coefficient (ECC), ECC+Rotation andthe method proposed by Griñón-Marín et al. (2020).

Para ello, se alinearon las imágenes usando el método Enhanced Correlation Coefficient (ECC),ECC+Rotación y el método propuesto por Griñón-Marín et al. (2020). Se utilizó la transformada de waveletpara extraer las potencias wavelet. Analizando la distribución de los períodos de oscilación de las potenciasde wavelet de forma local y global, no se identificó un periodo dominante en dichas potencias. También, seobtuvo una atenuación en las potencias Doppler del 22,1% y 41,6% respecto a las potencias obtenidas através del método ECC+Rotación para las potencias encontradas usando el método ECC y el método deGriñón-Marín et al. (2020). Además, no se encontró una correlación entre las potencias correspondientes alas velocidades Doppler y magnitud del campo magnético en la línea de la visión para los tres métodos dealineación.application/pdfspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ciencia_en_desarrollo/article/view/15245/12663Ciencia En Desarrollo; Vol. 1 No. 2E (2022): Núm. 2E (2022): Número Especial: VII Congreso de Astronomía y Astrofísica 2022; 55-62Ciencia en Desarrollo; Vol. 1 Núm. 2E (2022): Núm. 2E (2022): Número Especial: VII Congreso de Astronomía y Astrofísica 2022; 55-622462-76580121-7488Sol: velocidades Doppler -Sol: campos magnéticos – Sol: oscilaciones – Sol: fotósfera – manchas solares.Sun: Doppler velocities -Sun: magnetic fields – Sun: oscillations – Sun: photosphere – sunspotso.Study of Doppler velocities and their relationship with Magnetic field oscillations in the penumbra of SunspotsEstudio de las velocidades Doppler y su relación con las oscilaciones del campo magnético en la penumbra de las manchas solaresinfo:eu-repo/semantics/articlehttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1http://purl.org/coar/access_right/c_abf2Ordoñez Araujo, Francisco J.Calvo Mozo, BenjamínCastellanos Durán, Sebastian J.001/15381oai:repositorio.uptc.edu.co:001/153812025-07-18 10:56:33.134metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
