Abstract:
Thanks to the recent very high precision photometry of red giants from
satellites such as Kepler, precise mass and radius values as well as
accurate information of evolutionary stages are already established by
asteroseismic approach for a large number of G-K giants. Based on the
high-dispersion spectra of selected such 55 red giants in the Kepler field
with precisely known seismic parameters (among which parallaxes are
available for nine stars), we checked the accuracy of the determination
method of stellar parameters previously applied to many red giants by
Takeda et al. (2008PASJ...60..781T 2008PASJ...60..781T), since it may be possible to
discriminate their complex evolutionary status by using the surface gravity
versus mass diagram. We confirmed that our spectroscopic gravity and the
seismic gravity satisfactorily agree with each other (to within ∼0.1 dex)
without any systematic difference. However, the mass values of He-burning
red clump giants derived from stellar evolutionary tracks (∼2-3 M☉)
were found to be markedly larger by ∼50 percent compared to the seismic
values (∼1-2 M☉) though such discrepancy is not seen for normal
giants in the H-burning phase, which reflects the difficulty of mass
determination from intricately overlapping tracks on the luminosity versus
effective temperature diagram. This consequence implies that the mass
results of many red giants in the clump region determined by Takeda et al.
are likely to be significantly overestimated. We also compare our
spectroscopically established parameters with recent literature values,
and further discuss the prospect of distinguishing the evolutionary status
of red giants based on the conventional (i.e. non-seismic) approach.
Description:
The targets in this investigation were exclusively taken from the
Mosser et al. (2012, J/A+A/540/A143) 218 RG in the Kepler field, for which
the evolutionary status is well established in asteroseismic manner along
with Rseis and Mseis. The observations of 42 stars (with their Kepler
magnitudes being ∼9-11 mag) selected from this list were carried out
on 2014 September 9 (UT) with the High Dispersion Spectrograph (HDS;
Noguchi et al. 2002PASJ...54..855N 2002PASJ...54..855N) placed at the Nasmyth platform of the
8.2-m Subaru Telescope, by which high-dispersion spectra covering
∼5100-7800 Å were obtained (with two CCDs of 2Kx4K pixels) in the
standard StdRa setting with the red cross disperser. In addition to these
Subaru/HDS data, we also used the spectra of Kepler RG published by
Thygesen et al. (2012, J/A+A/543/A160), which they obtained with Nordic
Optical Telescope (NOT; R∼67000, 3700-7300 Å, S/N∼80-100),
Canada-France-Hawaii Telescope (CFHT; R∼80000, 3700-10500 Å, S/N∼200),
and Telescope Bernard Lyot (TBL; R∼75000, 3700-10500 Å, S/N∼200).
Since 16 stars (out of their 82 stars) are included in the Mosser et al.
(2012, J/A+A/540/A143) list (218 stars), we used their spectra for
these 16 stars.
