Questions
- Q: Mass segregation? Do you expect such a large number of stars kicked out?
- A: Yes. High density of massive stars in cores, 3-body interaction common there
- Q: NIII and HeII lines? Stellar wind effects move the centroid
- Q: Radial velocities are isolated stars on one side of Arches cluster. Is
that expected?
- A: I don't know if we expect that.
- Q: What stellar masses of escaped stars?
- A: Not measured yet.
- A Cornelia: many are radio-continuum detected. Consistent with stellar wind predictions
- Q Farhad: Star formation rate from runaways?
- A: Half of the stars come from clusters. Double the SFR from the clusters. 0.05 Msun/yr
- Q Mark Pound (?): Orbital histories. Are any of the orbits more likely than the others?
- A: Some could have been members.
