On the mass-to-light ratio of the local Galactic disc and the optical luminosity of the Galaxy
- C. Flynn, J. Holmberg, L. Portinari, B. Fuchs, H. Jahreiss
- Physics
- 9 August 2006
We measure the volume luminosity density and surface luminosity density generated by the Galactic disc, using accurate data on the local luminosity function and the vertical structure of the disc.… Expand
The local density of matter mapped by hipparcos
- J. Holmberg, C. Flynn
- Physics
- 22 December 1998
We determine the velocity distribution and space density of a volume-complete sample of A and F stars, using parallaxes and proper motions from the Hipparcos satellite. We use these data to solve for… Expand
The colours of the sun
- J. Holmberg, C. Flynn, L. Portinari
- Physics
- 6 November 2005
We compile a sample of Sun-like stars with accurate effective temperatures, metallicities and colours (from the ultraviolet to the near-infrared). A crucial improvement is that the effective… Expand
Distance to NGC 253 based on the planetary nebula luminosity function
We identify a sample of 14 planetary nebulae in the nearby starburst disc galaxy NGC 253, using broad- and narrow-band imaging. A simple model of the stellar and dust layers in the galaxy shows that… Expand
The local surface density of disc matter mapped by Hipparcos
- J. Holmberg, C. Flynn
- Physics
- 9 May 2004
We determine the surface density of matter in the disc of the Galaxy at the solar position using K giant stars. The local space density and luminosity function of the giants is determined using… Expand
M dwarfs: effective temperatures, radii and metallicities
- L. Casagrande, C. Flynn, M. Bessell
- Physics
- 15 June 2008
We empirically determine effective temperatures and bolometric luminosities for a large sample of nearby M dwarfs, for which high accuracy optical and infrared photometry is available. We introduce a… Expand
The inner halo of M 87: a first direct view of the red-giant population
- Sarah A. Bird, W. Harris, J. Blakeslee, C. Flynn
- Physics
- 16 September 2010
An unusually deep (V, I) imaging dataset for the Virgo supergiant M 87 with the Hubble Space Telescope ACS successfully resolves its brightest red-giant stars, reaching M I (lim) = ―2.5. After… Expand
The host galaxy of a fast radio burst
- E. Keane, S. Johnston, +38 authors C. Bassa
- Physics, Medicine
- Nature
- 25 February 2016
In recent years, millisecond-duration radio signals originating in distant galaxies appear to have been discovered in the so-called fast radio bursts. These signals are dispersed according to a… Expand
A real-time fast radio burst: polarization detection and multiwavelength follow-up
- E. Petroff, M. Bailes, +32 authors C. Wolf
- Physics
- 1 December 2014
Fast radio bursts (FRBs) are one of the most tantalizing mysteries of the radio sky; their progenitors and origins remain unknown and until now no rapid multiwavelength follow-up of an FRB has been… Expand
The helium abundance and ΔY/ΔZ in lower main-sequence stars
- L. Casagrande, C. Flynn, +4 authors Upenn
- Physics
- 29 March 2007
We use nearby K dwarf stars to measure the helium-to-metal enrichment ratio ΔY/ΔZ, a diagnostic of the chemical history of the solar neighbourhood. Our sample of K dwarfs has homogeneously determined… Expand
