The amount of astronomical data is rapidly growing as the progress of telescope technology and the detection technique of recent years. As a result, the way of traditional analysis is becoming insufficient for utilizing the large amount of data ef...
The metallicities and abundance ratios, [ X/ Fe], of 12 elements - C, Na, Mg, Si, S, Ca, Ti, Cr, Ni, Y, Zr, and Ce - are determined for 14 old and 24 young metal-rich stars based on high resolution, high S/ N spectra obtained with the HIDES spectr...

Flares are releases of magnetic energy in the stellar atmosphere, and they have strong emissions from radio to X-rays. During some M dwarf flares, chromospheric line profiles show blue asymmetries, although red asymmetries are more commonly observ...
Solar and stellar flares are caused by the sudden release of magnetic energy on the surfaces. In the case of the Sun, mass ejections often accompany solar flares and affect the Earth’s environment. Active solar-type stars (G-type main-sequence sta...
