Estimating Ion Temperatures at the Polar Coronal Hole Boundary
The Astrophysical Journal, 2023 The temperatures of the heavy ions ( T _i ) in the solar corona provide critical information about the heating mechanism of the million-degree corona.

Chromosphere Activity Relation with Solar Dynamo Magnetic Activity Cycle [PDF]
Iranian Journal of Astronomy and Astrophysics, 2022 In this article, we analyzed the abnormal thickness of the chromosphere above the coronal holes (CH) at the poles of the Sun for 13 years (2010-2022), on the 15th of every month, by using AIA/SDO telescope data.

Australian Journal of Physics, 1983 The dynamics of high speed streams of solar plasma emanating from a coronal hole is investigated by use of a two-fluid model with polytropic equations of state. Steady outflow is considered along a flow tube which has a radial orientation with respect to the Sun, and a cross-sectional area proportional to r' where r is the heliocentric radius and s is ...

Topologically driven coronal dynamics – a mechanism for coronal hole jets [PDF]
Annales Geophysicae, 2008 Abstract. Bald patches are magnetic topologies in which the magnetic field is concave up over part of a photospheric polarity inversion line. A bald patch topology is believed to be the essential ingredient for filament channels and is often found in extrapolations of the observed photospheric field.

Combined Management of Meniscus Root Tear and High Tibial Osteotomy: A Surgical Strategy Using 3‐Dimensional Printing [PDF]
Arthrosc TechAbstract Combining high tibial osteotomy with meniscal posterior root repair is technically challenging because of the limited metaphyseal bone stock, the proximity of the transtibial tunnel to the osteotomy site, and the risk of implant conflict or tibial fracture.

The Astrophysical Journal, 1975 It has been noted that coronal holes appear to be associated with regions of diverging magnetic field in the corona. We set out to test the hypothesis that coronal holes may be caused by an increased flow of energy into the solar wind resulting directly from this diverging magnetic field pattern.

MHD turbulence and heating of the open field-line solar corona [PDF]
, 2003 This paper discusses the possibility that heating of the solar corona in open field-line regions emanating from coronal holes is due to a nonlinear cascade, driven by low-frequency or quasi-static magnetohydrodynamic fluctuations.

Empirical Forecast of Corotating Interacting Regions and Geomagnetic Storms Based on Coronal Hole Information [PDF]
Journal of Astronomy and Space Sciences, 2009 In this study, we suggest an empirical forecast of CIR (Corotating Interaction Regions) and geomagnetic storm based on the information of coronal holes (CH). For this we used CH data obtained from He I 10830 Å maps at National Solar Observatory-Kitt Peak

On the Association between Coronal Mass Ejections and Coronal Holes [PDF]
International Astronomical Union Colloquium, 1989 AbstractThe coronal mass ejection (CME) data and the data for coronal holes for the period 1979-1982 are compared locationwise. Out of 79 CMEs whose locations and spans are known, 48 (61%) CMEs are associated with coronal holes. We make a tentative suggestion that probably the mass ejected during solar flares and active prominences may move along the ...
