J/ApJ/703/894 PNe in 5 nearby galaxies (Herrmann+, 2009) ================================================================================ Planetary nebulae in face-on spiral galaxies. II. Planetary nebula spectroscopy. Herrmann K.A., Ciardullo R. =2009ApJ...703..894H ================================================================================ ADC_Keywords: Galaxies, nearby ; Planetary nebulae ; Spectroscopy Keywords: galaxies: individual (IC 342, NGC 628, NGC 5236, NGC 4736, NGC 5457) - galaxies: kinematics and dynamics - galaxies: spiral - planetary nebulae: general Abstract: As the second step in our investigation of the mass-to-light ratio of spiral disks, we present the results of a spectroscopic survey of planetary nebulae (PNe) in five nearby, low-inclination galaxies: IC 342, M74 (NGC 628), M83 (NGC 5236), M94 (NGC 4736), and M101 (NGC 5457). Using 50 setups of the WIYN/Hydra and Blanco/Hydra spectrographs, and 25 observations with the Hobby-Eberly Telescope's Medium Resolution Spectrograph, we determine the radial velocities of 99, 102, 162, 127, and 48 PNe, respectively, to a precision better than 15km/s. Although the main purpose of this data set is to facilitate dynamical mass measurements throughout the inner and outer disks of large spiral galaxies, our spectroscopy has other uses as well. Here, we co-add these spectra to show that, to first order, the [OIII] and Balmer line ratios of PNe vary little over the top ~1.5mag of the PN luminosity function. Description: Our Hydra spectroscopy in the north was performed with the 3.5m WIYN telescope at Kitt Peak during six separate runs between 2003 March and 2007 November. For our southern (M83) observations, we used the version of Hydra on the CTIO 4m Blanco telescope. Finally, to supplement our Hydra observations, we targeted some of the M101 PNe with the Medium Resolution Spectrograph of the queue-scheduled HET.
