Sunspot umbral oscillations in the photosphere and low chromosphere
Bruce W. Lites,John H. Thomas +1 more
TL;DR: In this article, the velocity power spectrum in one spectral line formed in the low photosphere and in another formed in low chromosphere, just above the temperature minimum, was found to exhibit both 5-min and 3-min oscillations, with the kinetic energy of the latter being at least 5 times greater in the lower photosphere than in the higher chromosphere.
Journal ArticleDOI
Stokes profile analysis and vector magnetic fields. IV. Synthesis and inversion of the chromospheric Mg I b lines
TL;DR: Les equations de transfert du rayonnement polarise sont resolues analytiquement dans un cadre non ETL pour tous les etats excites des raies chromospheriques as mentioned in this paper.
Journal ArticleDOI
Performance characteristics of the Advanced Stokes Polarimeter
TL;DR: In this article, Lites, Martinez Pillet, and Skumanich pointed out some limitations of vector magnetometry by the use of a generic filter magnetograph and made incorrect statements regarding the performance characteristics of the Advanced Stokes Polarimeter (ASP).
Journal ArticleDOI
The interaction of solar p-modes with a sunspot. I - Observations
TL;DR: In this paper, time series of velocity maps of two isolated sunspots and their surroundings were recorded in the Fe I line and the umbral line Ti I. Both 3 and 5 min umbral oscillations were detected at photospheric heights.
Journal ArticleDOI

TL;DR: In this paper, the Spectro-Polarimeter of the Solar Optical Telescope (SOT) was used to observe magnetic fields of the Sun near disk center using the Hinode satellite, revealing the ubiquitous presence of horizontal magnetic fields in the internetwork regions.
