Abstract:
We present the results of a study of forbidden [OI]6300Å emission
line profiles in classical T Tauri stars in the young, open cluster
NGC 2264. We separate each of these profiles into up to four features
via Gaussian decomposition: narrow and broad low-velocity components
and blue- and redshifted high-velocity components. We study the
luminosities and kinematic properties of these components along with
known stellar and accretion parameters, in order to investigate their
origins.
Description:
Four tables are presented with the stellar and [OI] line parameters of
the stars used in our study.
tablec1.dat gives stellar parameters (spectral types, stellar
luminosities, masses and radii) for weak-lined T Tauri stars that were
used as photospheric templates.
tablec2.dat gives the same stellar parameters for the classical
T Tauri stars, besides their rotation periods, radial velocities,
vsini, inclinations derived from rotational properties, as well as
their accretion properties (mass accretion rates, accretion
luminosities and optical veiling) and properties of their
circumstellar disks (alphaIRAC indexes and infra-red excess).
tablec3.dat presents properties of the different components of the
detected [OI]6300Å line profiles (equivalent widths, centroid
velocities and FWHM).
tablec4.dat presents the luminosities of the different components of
the detected [OI]6300Å line profiles and jet velocities derived from
the detected high-velocity components.
