Stellar Chromospheric Activity Database of Solar-like Stars Based on the LAMOST Low-Resolution Spectroscopic Survey III. Calibrating the Chromospheric Basal Flux and the Connection to Stellar Rotation

Weitao Zhang, Han He, Jun Zhang

Based on the Ca\,II H and K lines observed by LAMOST, we employ the photospheric ( $R_{HK}^{'}$ ) and basal ( $R_{HK, L}^{+}$ ) flux calibrated chromospheric activity indices to exam…

Stellar Chromospheric Activity Database of Solar-like Stars Based on the LAMOST Low-Resolution Spectroscopic Survey: II. the bolometric and photospheric calibration

Weitao Zhang, Jun Zhang, Han He +2

The dependence of stellar magnetic activity on stellar parameters would be inspired by the chromospheric activity studies based on the large-scale spectroscopic surveys. The Ca II…
