- <p>This dataset contains the numerical thermal evolution models shown in Fig. A1<br>and summarized in Table 3 of the associated Astronomy & Astrophysics article<br>“Contrasting neutron star heating mechanisms with Hubble Space Telescope observations”.</p> <p>The models correspond to surface temperature evolution curves for the following pulsars:<br>PSR J0437−4715, PSR J2124−3358, PSR B0950+08, PSR J0108−1431, and PSR J2144−3933.</p> <p>----------------------------------------------------------------------<br>DATA FORMAT<br>----------------------------------------------------------------------</p> <p>The file j0437_ZENODOmodels.csv contains one table with paired columns for each model.<br>For each model label (I, II, III, …, XI), two columns are provided:</p> <p> <LABEL>_t : log10(t / yr)<br> <LABEL>_Tinf : log10(T_s^∞ / K)</p> <p>Different models may have different time sampling. Missing values are represented as NaN.</p> <p>The initial time point is explicitly set to t = 0 (i.e. log10(t) = 0).<br>In the original simulations, arrays were preallocated and padded with zeros beyond the<br>physical end of the evolution. When taking logarithms, these padded zeros produced<br>−Inf values. During post-processing for this dataset, such non-physical values were<br>removed and replaced by NaN, so that no ±Inf values appear in the released data.</p> <p>----------------------------------------------------------------------<br>PHYSICAL ASSUMPTIONS<br>----------------------------------------------------------------------</p> <p>All curves were computed assuming magnetic dipole spin-down with a constant dipole<br>moment inferred from the observed spin period P and spin-down rate Ṗ of each pulsar.</p> <p>For the millisecond pulsars (MSPs: J0437−4715 and J2124−3358), the initial conditions are:<br> P0 = 1 ms<br> T0^∞ = 10^9 K</p> <p>For the classical pulsars (CPs: B0950+08, J0108−1431, and J2144−3933), the initial conditions are:<br> P0 = 5 ms<br> T0^∞ = 10^11 K</p> <p>PSRs B0950+08 and J0108−1431 are plotted together and share the same inferred dipole<br>magnetic field (that of B0950+08).</p> <p>Observed temperatures, 1σ error bars, and upper limits are shown in the figures at the<br>times when the present-day spin parameters are reached.</p> <p>----------------------------------------------------------------------<br>MODEL LABELS<br>----------------------------------------------------------------------</p> <p>The column labels correspond to the following physical models (see Tables 2 and 3 of the paper):</p> <p>I Passive cooling with Murca reactions in normal (non-superfluid, non-superconducting) matter.</p> <p>II Passive cooling with Durca reactions in normal matter.</p> <p>III Rotochemical heating with Murca reactions in normal matter.</p> <p>IV Rotochemical heating with Durca reactions in normal matter.</p> <p>V Vortex creep with Murca reactions, assuming normal particles in the core and<br> an excess angular momentum parameter J = 3 × 10^43 erg s.</p> <p>VI Same as V, but with Durca reactions.</p> <p>VII Crustal heating (present only in MSPs) with Murca reactions and normal particles<br> in the core.</p> <p>VIII Same as VII, but with Durca reactions.</p> <p>IX Rotochemical heating with Murca reactions, assuming normal protons and superfluid<br> neutrons with a uniform energy gap Δ_n = 1.5 MeV, and reaction rates reduced by<br> a factor f = 10^−2.</p> <p>X Same as IX, but with Durca reactions and reaction rates reduced by a factor f = 10^−8.</p> <p>XI Rotochemical heating with Murca reactions assuming normal protons and superfluid<br> neutrons with Δ_n = 1.5 MeV and reaction rates reduced by a factor f = 10^−2,<br> combined with vortex creep with J = 3 × 10^43 erg s.</p> <p>----------------------------------------------------------------------<br>REFERENCE<br>----------------------------------------------------------------------</p> <p>If you use these data, please cite the associated A&A article.</p>
