The Sun at millimeter wavelengths IV. Magnetohydrodynamic waves in small-scale bright features

Juan Camilo Guevara Gómez, Shahin Jafarzadeh, Sven Wedemeyer +3

We used solar observations of a plage/enhanced network with the Atacama Large Millimeter/sub-millimeter Array (ALMA) in Band 3 and Band 6 together with synthetic continuum maps fro…

The effects of stellar rotation along the main sequence of the 100 Myr old massive cluster NGC 1850

Sebastian Kamann, Sara Saracino, Nate Bastian +13

Young star clusters enable us to study the effects of stellar rotation on an ensemble of stars of the same age and across a wide range in stellar mass and are therefore ideal targe…

MINDS. The detection of CO with JWST-MIRI indicates abundant CO in a protoplanetary disk

Sierra L. Grant, Ewine F. van Dishoeck, Benoît Tabone +43

We present JWST-MIRI MRS spectra of the protoplanetary disk around the low-mass T Tauri star GW Lup from the MIRI mid-INfrared Disk Survey (MINDS) GTO program. Emission from $^{12}…

Center-to-limb variation of spectral lines and continua observed with SST/CRISP and SST/CHROMIS

A. G. M. Pietrow, D. Kiselman, O. Andriienko +3

Observations of center-to-limb variations (CLV) of spectral lines and continua provide a good test for the accuracy of models of solar and stellar atmospheric structure and spectra…

Deep solar ALMA neural network estimator for image refinement and estimates of small-scale dynamics

Henrik Eklund

The contrasts and magnitude of observable signatures of small-scale features degrade as angular resolution decreases. High-cadence time-series of synthetic observable maps at 1.25…

Chromospheric Heating from Local Magnetic Growth and Ambipolar Diffusion Under Non-Equilibrium Conditions

Juan Martínez Sykora, Jaime de la Cruz Rodríguez, Milan Gošić +3

The heating of the chromosphere in internetwork regions remains one of the foremost open questions in solar physics. In the present study we tackle this old problem by using a very…
