Thermal luminosities of cooling neutron stars
Mon. Not. R. Astron. Soc. 496, 5052-5071 (2020)

Notations:
P — spin period
dP/dt — spin period time-derivative
Bdip — characteristic magnetic field (i.e., equatorial magnetic field estimate according to the canonical dipole model)
tc — characteristic age
t* — age, estimated independently on timing
L33 — redshifted (i.e., in the frame of a remote observer) thermal luminosity in units of 10³³ erg/s
Tinf — redshifted effective temperature (in energy units, eV).
min — lower limit
mid — most probable value (or the middle of the age interval, if it is firmly known)
max — upper limit
 ---  — unknown or poorly constrained or non-applicable

If there are two (or more) components of the spectral fit that contribute to the thermal luminosity (L33) substantially (by > 15% each), the lower limit (min) for the temperature (Tinf) is given for the coldest component and the upper limit (max) for the hottest component.

References are coded by the latters as follows:
D - a reference for distance,
T - a reference for timing: P, dP/dt, Bdip, tc (such references are not given if the timing data are taken from the ATNF Pulsar Catalog),
A - a reference for age t*,
S - a reference for spectral analysis: L33, Tinf.
The citations pop up when hovering the cursor on these letters. Whenever possible, they are hyperlinked to relevant Web pages (in most cases, to the corresponding page in the NASA ADS).

For the entries that have been updated after the original publication, the last column shows the date of the last update (described below the table).

====================================================================================================================================================================================================

• 09.08.2020 - updated L33 and Tinf for PSR J1957+5033 (a preliminary version of Zyuzin et al. 2021).
• 14.09.2020 - fixed typo in Bdip for RX J2143.0+0654.
• 26.09.2020 - small updates to L33 and Tinf for PSR J1957+5033 according to Zyuzin et al. (2021)
• 25.11.2020 - 1E 0102.2-7219 is excluded from the list, since an evidence has emerged that it is not a neutron star: Long et al. (2020).
• 01.02.2021 - updated L33 and Tinf for PSR B0656+14 according to the most confident model N2 of Zharikov et al. (2021).
• 09.08.2021 - the age of XMMU J172054.5-372652 is restricted to be <700 yr according to Mayer & Becker (2021).
• 25.08.2021 - L33 and Tinf for CXOU J160103.1-513353, 1WGA J1713.4-3949, and XMMU J172054.5-372652 are updated according to Tables 4, 5, and 7 of Ho et al. (2021). L33 and Tinf are derived from local temperatures and effective emitting areas given in these tables for the carbon atmosphere ("nsx") model fitting. This model is preferred because it gives more plausible effective radii than the other models in the tables, with nearly the same statistical quality. The distances are assumed fixed as per the authors. For 1WGA J1713.4-3949, the data presented by the authors for three observation series (performed in 2001, 2004, and 2014) are averaged, and the uncertainties are enlarged to embrace the uncertainties of all the three sets.
• 02.11.2021 - distance, L33 and Tinf of 1RXS J141256.0+792204 "Calvera" are restricted according to Table 3 of Mereghetti et al. (2021).
• 20.12.2021 - updated distance, L33, and Tinf for PSR J1957+5033 (Zyuzin et al. 2022).
• 25.04.2022 - L33 and Tinf for PSR J1740+1000 are updated according to Rigoselli et al. (2022); L33 is estimated based on the values of Tinf and radius for the two blackbody components.
• 29.04.2022 - added PSR B0950+08 (PSR J0953+0755) according to Abramkin et al. (2022). The age t_k is taken from Igoshev (2019), and its uncertainty is enlarged to include t_k from Noutsos et al. (2013) who used an alternative prior velocity distribution model for the Bayesian age estimate.
• 05.08.2022 - added PSR J0554+3107 according to Tanashkin et al. (2022).
• 14.10.2022 - slightly improved timing (dP/dt, tc) of RX J1856.5-3754 by De Grandis et al. (2022).
• 21.10.2022 - corrected timing data (P, dP/dt, Bdip) of RX J0720.4-3125 according to Hambaryan et al. (2017), who argue that the genuine period is twice longer than listed in the ATNF Pulsar Catalogue.
• 02.11.2022 - updated distance, luminosity, and effective temperature for XMMU J173203.3-344518, following Doroshenko et al. (2022). The effective redshifted temperature Tinf=156±6 eV is derived from the local effective temperature, mass, and local radius (with 1σ uncertainties) for the spectral model carbatm₁ (the only model that assumes a uniform temperature) in Table 1 of Doroshenko et al. (2022). From the same table, we estimate L33=10.6^+2.1_-1.7, 10.8^+3.7_-3.0, and 10.8±0.8 for models carbatm₁, carbatm₂, and hatm₂, respectively; the second of these estimates is adopted as representative here.
• 13.11.2022 - updated data for the neutron star in Cassiopeia A: the age, luminosity, and redshifted temperature ranges are adjusted so as to embrace the data listed by Ho et al. (2021) and Posselt & Pavlov (2022) for different observations from 2006 to 2020, fitted with neutron star models with carbon atmospheres (see the original publications for the time-resolved data).
• 23.03.2023 - changes of 18.07.2021 to t* for PSR J0538+2817, PSR B0656+14, and PSR B2334+61 have been reverted following a discussion with colleagues.
• 03.07.2024 - updated timing data for XINSs RX J0420.0-5022, RX J0720.4-3125, RX J0806.4-4123, and RX J2143.0+0654 according to Bogdanov & Ho (2024).
