Aqueye+ runs of PSR J1023+0038 carried out between January 2021 and December 2023.
| Aqueye+ run | t0 (MJD) | ΔTasc (s) | Tasc (MJD) | Pspin (s) |
|---|---|---|---|---|
| Jan. 2021 | 59226.0 | 44.35 ± 0.17 | 59226.055461 | 0.0016879874467 ± 4.4×10−13 |
| Jan. 2023 | 59965.0 | 81.05 ± 1.23 | 59964.756622 | 0.0016879874472 ± 9.0×10−13 |
| Dec. 2023 | 60290.0 | 97.33 ± 1.39 | 60290.030772 | 0.0016879874474 ± 1.1×10−12 |
Notes. Aqueye+ runs of PSR J1023+0038, carried out at the 1.82 m Copernicus telescope. The reference epoch (Tref) corresponds to the start time of each run. The ΔTasc are calculated for the value reported in Ambrosino et al. (2017). The spin periods of January and December 2023 are those extrapolated from the long-term timing solution of Burtovoi et al. (2020), at the time of our observations.
