Sunspots: an overview

SK Solanki - The Astronomy and Astrophysics Review, 2003 - Springer
Sunspots are the most readily visible manifestations of solar magnetic field concentrations
and of their interaction with the Sun's plasma. Although sunspots have been extensively …

Chromospheric damping of Alfvén waves

B De Pontieu, PCH Martens… - The Astrophysical …, 2001 - iopscience.iop.org
We analytically study the damping of Alfvén mode oscillations in the chromosphere and in
coronal loops. In the partially ionized chromosphere the dominant damping process of …

Non-LTE inversion of Stokes profiles induced by the Zeeman effect

H Socas-Navarro, JT Bueno… - The Astrophysical …, 2000 - iopscience.iop.org
This paper presents a new diagnostic tool for the inference of the thermal, dynamic, and
magnetic properties of the solar chromosphere. It consists of a non-LTE inversion code of …

[HTML][HTML] Observed differences between large and small sunspots

M Collados, V Martínez Pillet… - … (ISSN 0004-6361) …, 1994 - adsabs.harvard.edu
We confirm recent results about the differences in temperature and magnetic field strength

Propagating slow magnetoacoustic waves in coronal loops observed by Hinode/EIS

TJ Wang, L Ofman, JM Davila - The Astrophysical Journal, 2009 - iopscience.iop.org
We present the first Hinode/EUV Imaging Spectrometer observations of 5 minute quasi-
periodic oscillations detected in a transition-region line (He ii) and five coronal lines (Fe x …

Chromospheric Height and Density Measurements in a Solar Flare Observed with RHESSI: II. Data Analysis

MJ Aschwanden, JC Brown, EP Kontar - The Reuven Ramaty High-Energy …, 2003 - Springer
We present an analysis of hard X-ray imaging observations from one of the first solar flares
observed with the Reuven Ramaty High-Energy Solar Spectroscopic Imager (RHESSI) …

Oscillations above sunspots: Evidence for propagating waves?

E O'shea, K Muglach, B Fleck - Astronomy & Astrophysics, 2002 - aanda.org
We present results of an analysis of time series data observed in sunspot umbral regions.
The data were obtained in the context of the SOHO Joint Observing Program (JOP) 97 in …
