Abstract:
PolarBase is an evolving data base that contains all stellar data collected
with the ESPaDOnS and NARVAL high-resolution spectropolarimeters, in their
reduced form, as soon as they become public. As of early 2014, observations of
2,000 stellar objects throughout the Hertzsprung-Russell diagram are
available. Intensity spectra are available for all targets, and the majority
of the observations also include simultaneous spectra in circular or linear
polarization, with the majority of the polarimetric measurements being
performed only in circularly polarized light (Stokes V). Observations are
associated with a cross-correlation pseudo-line profile in all available
Stokes parameters, greatly increasing the detectability of weak polarized
signatures. Stokes V signatures are detected for more than 300 stars of all
masses and evolutionary stages, and linear polarization is detected in 35
targets. The detection rate in Stokes V is found to be anti-correlated with
the stellar effective temperature. This unique set of Zeeman detections offers
the first opportunity to run homogeneous magnetometry studies throughout the
H-R diagram. The web interface of PolarBase is available at
http://polarbase.irap.omp.eu.
Description:
We list the stellar spectroscopic and spectropolarimetric observations
available in the PolarBase data base. For each star equatorial
coordinates, first Julian date of observation, last Julian date of
observation, number of observations are given, and a detection
diagnosis of polarized signatures (in cross-correlated pseudo-line
profiles) are given.
