Solar surface rotation: N-S asymmetry and recent speed-up
, 2015 Context. The relation between solar surface rotation and sunspot activity is still not fully resolved. The sunspot activity has been significantly reduced in solar cycle 24, and several solar activity indices and flux measurements experienced ...

Mechatronics Application to Solar Tracking
, 2011 The purpose of this was to design and implement a two-axis solar tracking system utilizing the National Instruments C-Rio real time controller. In order to accomplish this a prototype was modeled in CAD. This prototype used two 12 V DC motors to change a

Differential rotation of solar
Context. Differential rotation is a key driver of magnetic activity and dynamo processes in the Sun and other stars, especially as the rate differs across the solar layers, and also in active regions. Aims.

Impact of anti-solar differential rotation in mean-field solar-type dynamos
, 2022 Context. Over the course of their lifetimes, the rotation of solar-type stars goes through different phases. Once they reach the zero-age main sequence, their global rotation rate decreases during the main sequence until at least the solar age ...

Efficient Screening of Organic Singlet Fission Molecules Using Graph Neural Networks
Advanced Science, EarlyView.A high‐throughput screening framework based on graph neural networks (GNNs) and multi‐level validation facilitates the identification of singlet fission (SF) candidates. By efficiently predicting excitation energies across 20 million molecules, and integrating TDDFT calculations, synthetic accessibility assessments, and GW+BSE calculations, this ...

ON THE SEPARATION OF SOLAR AND LUNAR CYCLES
Odessa Astronomical Publications, 2014 The synodic rotation period of the Sun nearly coincides with the sidereal rotation period of the Moon (27.3 days). The 11-year cycle of solar activity coincides with the eclipse cycle Tritos.

The Effects of Differential Rotation on the Magnetic Structure of the Solar Corona: MHD Simulations
, 2004 Coronal holes are magnetically open regions from which the solar wind streams. Magnetic reconnection has been invoked to reconcile the apparently rigid rotation of coronal holes with the differential rotation of magnetic flux in the photosphere.
