The catalogued J2000 position is carried along the great circle the object's own published motion puts it on, at a constant velocity, and the result is referred to the true equator and equinox of this instant. Those are separate things: the motion moves the object, and the rotation turns the grid under it by about fifty arcseconds a year, with nutation adding up to another seventeen.","excluded":"Parallax, the radial-velocity perspective term, aberration and refraction; each is below the accuracy of the catalogued positions themselves. An object with no published proper motion comes back where the catalogue has it rather than at a fabricated zero, and says so with a null pm_ra_mas_yr. A body with no fixed position is not propagated at all — its place comes from an ephemeris, which is what /api/v1/visible answers with."},"slug":"psr-j1432m5032","name":"PSR J1432-5032","class":"pulsar","category":"neutron_star","object_type":"Pulsar","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":17221.056743444053,"distance_method":"dispersion measure through the YMW16 electron-density model","ra_deg":218.21779166666664,"dec_deg":-50.53813888888889,"epoch_ra_deg":218.673123,"epoch_dec_deg":-50.656752,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Lupus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/psr-j1432m5032","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"spin_period_s":2.0349894792,"spin_period_derivative":5.924e-15,"radio_flux_1400_mhz_mjy":0.3,"characteristic_age_years":5442684.446110283,"dispersion_measure_pc_cm3":113,"spin_down_luminosity_erg_s":2.775161626720365e+31,"surface_magnetic_field_gauss":3513488912601.766},"designations":[{"catalog":"ATNF","designation":"J1432-5032"},{"catalog":"ATNF","designation":"PSR J1432-5032"}],"source":{"id":"atnf","name":"ATNF Pulsar Catalogue (Manchester+ 2005)","url":"https://www.atnf.csiro.au/research/pulsar/psrcat","license":"Free to use with attribution; cite Manchester+ 2005 (2005AJ....129.1993M)"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
