Abstract:
Fundamental parameters characterizing the end-state of
intermediate-mass stars may be constrained by discovering planetary
nebulae (PNe) in open clusters (OCs). Cluster membership may be
exploited to establish the distance, luminosity, age, and physical
size for PNe, and the intrinsic luminosity and mass of its central
star.
Four potential PN-OC associations were investigated to assess the
cluster membership for the PNe.
Radial velocities were measured from intermediate-resolution optical
spectra, complemented with previous estimates in the literature.When
the radial velocity study supported the PN/OC association, we analyzed
whether other parameters (e.g., age, distance, reddening, central star
brightness) were consistent with this conclusion.
Description:
The spectra were collected on 2012-04-13 with the B&C spectrograph at
the focus of the 2.5m du Pont telescope at the Las Campanas
observatory. The 1200 line/mm grating was used at the second order,
with a grating angle of 56.12°, thus collecting data in the
spectral interval 596-666nm.
