Is our Sun a Singleton?
D. Malmberg, M. B. Davies, J. E. Chambers +4
Most stars are formed in a cluster or association, where the number density of stars can be high. This means that a large fraction of initially-single stars will undergo close enco…
Planetary Nebula Velocities in the Disk and Bulge of M31
C. Halliday, D. Carter, T. J. Bridges +10
We present radial velocities for a sample of 723 planetary nebulae (PNe) in the disk and bulge of M31, measured using the WYFFOS fibre spectrograph on the William Herschel telescop…
Tracing the Star Stream Through M31 Using Planetary Nebula Kinematics
H. R. Merrett, K. Kuijken, M. R. Merrifield +12
We present a possible orbit for the Southern Stream of stars in M31, which connects it to the Northern Spur. Support for this model comes from the dynamics of planetary nebulae (PN…
New Mass Estimators for Tracer Populations
N. W. Evans, M. I. Wilkinson, K. M. Perrett +1
We introduce the tracer mass estimator. This is a new and simple way to estimate the enclosed mass from the projected positions and line of sight velocities of a tracer population…
Dynamical Mass Estimates for the Halo of M31 from Keck Spectroscopy
N. W. Evans, M. I. Wilkinson, P. Guhathakurta +2
The last few months have seen the measurements of the radial velocities of all of the dwarf spheroidal companions to the Andromeda galaxy (M31) using the spectrographs (HIRES and L…
The Mass of the Andromeda Galaxy
N. W. Evans, M. I. Wilkinson
This paper argues that the Milky Way galaxy is probably the largest member of the Local Group. The evidence comes from estimates of the total mass of the Andromeda galaxy (M31) der…
