The continuous observation of the magnetic field by Solar Dynamics Observatory (SDO)/Helioseismic and Magnetic Imager (HMI) produces numerous image sequences in time and space. The…
Generalized split monopole magnetospheres: the effects of current sheets
Huiquan Li, Jiancheng Wang
We show that energy should be dissipated or extracted in the current sheet (CS) of a split magnetosphere deviating from the Michel split monopole, with the CS heating up or cooling…
Construction and On-site Performance of the LHAASO WFCTA Camera

ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): Detection of extremely high density compact structure of prestellar cores and multiple substructures within
Dipen Sahu, Sheng-Yuan Liu, Tie Liu +38
Prestellar cores are self-gravitating dense and cold structures within molecular clouds where future stars are born. They are expected, at the stage of transitioning to the protost…
Magnetic reconnection between loops accelerated by a nearby filament eruption
Leping Li, Hardi Peter, Lakshmi Pradeep Chitta +3
Magnetic reconnection modulated by non-local disturbances in the solar atmosphere has been investigated theoretically, but rarely observed. In this study, employing Ha and extreme…
The hyperluminous, dust-obscured quasar W2246-0526 at z=4.6: detection of parsec-scale radio activity
Lulu Fan, Wen Chen, Tao An +4
WISE J224607.56052634.9 (W2246-0526) is a hyperluminous (), dust-obscured and radio-quiet quasar at redshift . It plays a ke…
Differential rotation of the chromosphere in the He I absorption line
KJ Li, JC Xu, JL Xie +1
Differential rotation is the basis of the solar dynamo theory. Synoptic maps of He I intensity from Carrington rotations 2032 to 2135 are utilized to investigate the differential r…
Spot Model for Identifications of Periods in Asynchronous Polars
Qishan Wang, Shengbang Qian, Zhongtao Han +3
We improved the discless accretion models of Wynn \& King, considering the effects of the changing aspect due to the white dwarf spin and the variable feeding intensity caused by t…
