The Left Panel Shows The Observed White Dwarf Cooling S The left panel shows the observed white dwarf cooling sequence of 47 tuc with the proper motion selected stars. the right panel shows the monte carlo simulation with 11.20 gyr, that best fitted. To assess this, we compare in fig. 3 the sorted list of goldsbury et al. (2012) with the theoretical cooling sequences of two white dwarfs of masses m wd = 0.525 m ⊙ and 0.520 m ⊙, the white dwarf mass corresponding to the main sequence turn off of 47 tuc, for two metallicities that embrace the metallicity of the cluster, z = 10 3 and z = 10 2, respectively.
The Left Panel Shows The Observed White Dwarf Cooling S We use new observations from the canada france hawaii telescope to study the white dwarf cooling sequence of the open cluster m37, a cluster that displays an extended main sequence turn off and. Panel (s2) shows a direct comparison of the cmds for sources surviving all the selection criteria: asts [as selected in panel (a5)] are shown in orange, while real sources [as selected in panel (r5)] are shown in blue. from this cmd, it is evident that the observed real wd cs does not extend to magnitudes as faint as those of the recovered asts – a clear indication that we have reached and. The left panel shows the observed white dwarf cooling sequence of 47 tuc with the proper motion selected stars. the right panel shows the monte carlo simulation with 11.20 gyr, that best fitted. Garc´ıa–berro et al.: the white dwarf cooling sequence of 47 tuc figure2. distribution of effective temperatures as a function of the white dwarf object number (left axis). the observationalval ues of goldsbury et al. (2012) are displayed using a grey shaded area, while the results of our monte carlo simulations are shown using red lines.

The fraction of calcium white dwarfs changes along the cooling sequence, increasing from f ca ≈0 at t eff= 13500 k to f ca ≈0.15 at t eff= 5500 k. this trend reflects the selection function of calcium white dwarfs in the optical. we compare our results with the fractions derived from the 40 pc spectroscopic sample and from sloan digital sky. White dwarfs are stellar remnants devoid of a nuclear energy source, gradually cooling over billions of years 1, 2 and eventually freezing into a solid state from the inside out 3, 4. recently, it.
