Reevaluating thermal instability in a uniform plasma: an extended analysis of instability domains
Varsha Felsy, Ramon Oliver, Jaume Terradas +3
Thermal instability plays a crucial role in the dynamics of astrophysical plasmas. Building upon the foundational work of G. B. Field (1965) and the subsequent analysis by T. Water…
Understanding coronal rain dynamics through a point-mass model
Andrew Hillier, Ramon Oliver, David Martínez-Gómez
Observations and simulations of coronal rain show that as cold and dense plasma falls through the corona it initially undergoes acceleration by gravity before the downward velocity…
Temperature diagnostics of chromospheric fibrils
M. Kriginsky, R. Oliver, D. Kuridze
Context. Chromospheric fibrils are thin and elongated structures that connect nearby photospheric magnetic field concentrations of opposite polarities. Aims. We assess the possibil…
Large ion-neutral drift velocities and plasma heating in partially ionized coronal rain blobs
David Martínez-Gómez, Ramón Oliver, Elena Khomenko +1
In this paper we present a numerical study of the dynamics of partially ionized coronal rain blobs. We use a two-fluid model to perform a high-resolution 2D simulation that takes i…
Dark off-limb gap: manifestation of temperature minimum and dynamic nature of the chromosphere
D. Kuridze, P. Heinzel, J. Koza +1
We study off-limb emission of the lower solar atmosphere using high-resolution imaging spectroscopy in the H and Ca II 8542 Å lines obtained with the CHROMospheric Imaging Spect…
The cyclic behaviour in the N-S asymmetry of sunspots and solar plages for the period 1910 to 1937 using data from Ebro catalogues
V. de Paula, J. J. Curto, R. Oliver
The heliophysics catalogues published by the Ebro Observatory during 1910--1937 have been converted into a digital format in order to provide the data for computational processing.…
