Solar science with the Atacama Large Millimeter/submillimeter Array - A new view of our Sun
S. Wedemeyer, T. Bastian, R. Brajsa +35
The Atacama Large Millimeter/submillimeter Array (ALMA) is a new powerful tool for observing the Sun at high spatial, temporal, and spectral resolution. These capabilities can addr…
Sausage, kink, and fluting MHD wave modes identified in solar magnetic pores by Solar Orbiter/PHI
S. Jafarzadeh, L. A. C. Schiavo, V. Fedun +25
Solar pores are intense concentrations of magnetic flux that emerge through the Sun's photosphere. When compared to sunspots, they are much smaller in diameter and hence can be imp…
Acoustic-gravity wave propagation characteristics in 3D radiation hydrodynamic simulations of the solar atmosphere
B. Fleck, M. Carlsson, E. Khomenko +3
There has been tremendous progress in the degree of realism of three-dimensional radiation magneto-hydrodynamic simulations of the solar atmosphere in the past decades. Four of the…
A novel approach to identify resonant MHD wave modes in solar pores and sunspot umbrae: analysis
M. Stangalini, D. B. Jess, G. Verth +12
The umbral regions of sunspots and pores in the solar photosphere are generally dominated by ~mHz oscillations, which are due to -modes penetrating the magnetic region. In th…
ALMA Observations of the Sun in Cycle 4 and Beyond
S. Wedemeyer, B. Fleck, M. Battaglia +34
This document was created by the Solar Simulations for the Atacama Large Millimeter Observatory Network (SSALMON) in preparation of the first regular observations of the Sun with t…
JHelioviewer - Time-dependent 3D visualisation of solar and heliospheric data
D. Mueller, B. Nicula, S. Felix +9
Context. Solar observatories are providing the world-wide community with a wealth of data, covering large time ranges, multiple viewpoints, and returning large amounts of data. In…
SSALMON - The Solar Simulations for the Atacama Large Millimeter Observatory Network
S. Wedemeyer, T. Bastian, R. Brajsa +27
The Solar Simulations for the Atacama Large Millimeter Observatory Network (SSALMON) was initiated in 2014 in connection with two ALMA development studies. The Atacama Large Millim…
High frequency waves in the solar atmosphere?
B. Fleck, T. Straus, M. Carlsson +3
The present study addresses the following questions: How representative of the actual velocities in the solar atmosphere are the Doppler shifts of spectral lines? How reliable is t…
On the influence of magnetic topology on the propagation of internal gravity waves in the solar atmosphere
G. Vigeesh, M. Roth, O. Steiner +1
The solar surface is a continuous source of internal gravity waves (IGWs). IGWs are believed to supply the bulk of the wave energy for the lower solar atmosphere, but their existen…
On the detection of fast moving upflows in the quiet solar photosphere
T. Straus, B. Fleck, S. M. Jefferies +2
In our studies of the dynamics and energetics of the solar atmosphere, we have detected, in high-quality observations from Hinode SOT/NFI, ubiquitous small-scale upflows which move…
The Signature of Flares in VIRGO Total Solar Irradiance Measurements
A. Quesnel, B. R. Dennis, B. Fleck +2
We use Total Solar Irradiance (TSI) measurements from the VIRGO (Variability of solar IRradiance and Gravity Oscillations) instrument on board SOHO to obtain preliminary estimates…
The Solar Orbiter Science Activity Plan: translating solar and heliospheric physics questions into action
I. Zouganelis, A. De Groof, A. P. Walsh +182
Solar Orbiter is the first space mission observing the solar plasma both in situ and remotely, from a close distance, in and out of the ecliptic. The ultimate goal is to understand…
