Abstract:
In our former paper I (Cretignier et al., 2024MNRAS.527.2940C 2024MNRAS.527.2940C, Cat.
J/MNRAS/527/2940), we showed on the Sun that different active regions
possess unique intensity profiles on the Ca II H & K lines. We now
extend the analysis by showing how those properties can be used on
real stellar observations, delivering more powerful activity proxies
for radial velocity correction. More information can be extracted on
rotational timescale from the Ca II H & K lines than the classical
indicators: S-index and log(R'HK). For high-resolution HARPS
observations of alpha Cen B, we apply a principal and independent
component analysis on the Ca II H & K spectra time-series to
disentangle the different sources that contribute to the
disk-integrated line profiles. While the first component can be
understood as a denoised version of the Mount-Wilson S-index, the
second component appears as powerful activity proxies to correct the
RVs induced by the inhibition of the convective blueshift in stellar
active regions. However, we failed to interpret the extracted
component into a physical framework. We conclude that a more complex
kernel or bandpass than the classical triangular of the Mount Wilson
convention should be used to extract activity proxies. To this regard,
we provide the first principal component activity profile obtained
across the spectral type sequence between M1V to F9V type stars.
Description:
We propose here below to extract the different activity components
on the spectra time-series of chromospheric lines such as the
Ca II H & K lines by using algorithms designed to solve the blind
source separation (BSS) problem.
