In the previous section, we described the migration of the producing region of the prominence activities using the butterfly diagram of prominence activities, and showed that the unusual migration in the southern hemisphere started from the solar ...

In the previous section, we have obtained the Galaxy center distance to be R0=8.05±0.45kpc, with the error bar including systematics due to possible “outliers”. This result is fully consistent with recent studies of R0. For instance, the review pa...

Both the spectra and distribution of the maser spots as shown in Figures 2 and 3 imply that the masers trace the base of the protostellar jet driven by the Class 0 source L1448C. In this section, we will discuss about the velocity structure of the...

This work provides a study of the effects of excited state β-decays on the r-process. A preliminary method was used to evaluate the possible effects of β-decay rates of excited-state nuclei. Though the accuracy of the model is limited by the knowl...

Our survey detected 441 asteroids in 13.6 deg2 at high ecliptic latitudes with a 50% limiting magnitude of r = 24.4 mag. We obtained an unbiased sample consisting of 221 MBA candidates with inclination of I ≳ 14\arcdeg and absolute magnitude of Hr...

As shown in section 1, the source at the tangent point has a kinematically unique property and one of the key objects to study the kinematics and geometry of the MWG. Due to a symmetric geometry, the radial velocity of a source at the tangent poin...
