| Abstract: |
We detected 848 polar X-ray jets occurred in the north polar region, and investigated the characteristics of the jets statistically.
The 470 jets of them occurred in the coronal hole. The occurrence rate of the jets in the coronal hole and the quiet region are
5.04×10-12 jets/hr/km2 and 7.66×10-12 jets/hr/km2, respectively. We derived five parameters of the
polar X-ray jets. The averaged values of the parameters are 2.91×104 km for the maximum length, 4.42×103 km for
the width, 608 sec for the lifetime and 180 km/sec for the apparent velocity.
If we assume that the frequency distribution of the lifetime and the footpoint flare show the power-law distributions, and the index is
-1.80 ± 0.20 in the coronal hole and -1.84 ± 0.17 in the quiet region. The frequency distribution is steeper than
that of the previous works. |
