Constraining the Systematics of (Acoustic) Wave Heating Estimates in the Solar Chromosphere [PDF]
The Astrophysical Journal, 2023 Acoustic wave heating is believed to contribute significantly to the missing energy input required to maintain the solar chromosphere in its observed state.

Why “Solar Tsunamis” Rarely Leave Their Imprints in the Chromosphere [PDF]
The Astrophysical Journal Letters, 2023 Solar coronal waves frequently appear as bright disturbances that propagate globally from the eruption center in the solar atmosphere, just like the tsunamis in the ocean on Earth.

An overall view of temperature oscillations in the solar chromosphere with ALMA. [PDF]
Philos Trans A Math Phys Eng Sci, 2021 By direct measurements of the gas temperature, the Atacama Large Millimeter/submillimeter Array (ALMA) has yielded a new diagnostic tool to study the solar chromosphere. Here, we present an overview of the brightness-temperature fluctuations from several

Effects of ambipolar diffusion on waves in the solar chromosphere [PDF]
Astronomy & Astrophysics, 2021 The chromosphere is a partially ionized layer of the solar atmosphere, the transition between the photosphere where the gas motion is determined by the gas pressure and the corona dominated by the magnetic field. We study the effect of partial ionization

The Formation Height of Millimeter-wavelength Emission in the Solar Chromosphere [PDF]
Astrophysical Journal, 2020 In the past few years, the ALMA radio telescope has become available for solar observations. ALMA diagnostics of the solar atmosphere are of high interest because of the theoretically expected linear relationship between the brightness temperature at ...

Heating of the solar chromosphere in a sunspot light bridge by electric currents [PDF]
Astronomy & Astrophysics, 2021 Context. Resistive Ohmic dissipation has been suggested as a mechanism for heating the solar chromosphere, but few studies have established this association. Aims.

Chromospheric Jets and Their Properties [PDF]
Iranian Journal of Astronomy and Astrophysics, 2022 In this study we review solar chromospheric jets and characteristics of them. The chromosphere and transition region are the interface between the solar photosphere and the corona, which plays a key role in the formation and acceleration of the solar ...

Heating of the solar chromosphere through current dissipation [PDF]
Astronomy & Astrophysics, 2022 The solar chromosphere is heated to temperatures higher than predicted by radiative equilibrium. This excess heating is greater in active regions where the magnetic field is stronger. We aim to investigate the magnetic topology associated with an area of

Numerical Simulations and Observations of Mg ii in the Solar Chromosphere [PDF]
Astrophysical Journal, 2022 The Mg ii h and k lines are among the best diagnostic tools of the upper solar chromosphere. This region of the atmosphere is of particular interest, as it is the lowest region of the Sun’s atmosphere where the magnetic field is dominant in the ...
