Abstract:
Stellar evolution is modified if energy is lost in a "dark channel"
similar to neutrino emission. Comparing modified stellar evolution
sequences with observations provides some of the most restrictive
limits on axions and other hypothetical low-mass particles and on
non-standard neutrino properties. In particular, a putative neutrino
magnetic dipole moment µν enhances the plasmon decay process,
postpones helium ignition in low-mass stars, and therefore extends the
red-giant branch (RGB) in globular clusters (GCs). The brightness of
the tip of the RGB (TRGB) remains the most sensitive probe for
µν and we revisit this argument from a modern perspective.
Based on a large set of archival observations, we provide
high-precision photometry for the Galactic GC M5 (NGC 5904) and
carefully determine its TRGB position.
Description:
We have carried out crowded-field, point-spread function (PSF)
photometry for M5 using the DAOPHOT II/ALLFRAME suite of programs
(Stetson 1987PASP...99..191S 1987PASP...99..191S, 1994PASP..106..250S 1994PASP..106..250S).
The current corpus of observations for M5 consists of 2840 CCD images
obtained during 40 observing runs on 12 telescopes over a span of 27
years (1984-2011)
