Titolo: | Large Binocular Telescope observations of PSR J2043+2740* | Autori: | TESTA, Vincenzo MIGNANI, Roberto Rea, N. MARELLI, MARTINO Salvetti, D. Breeveld, A. A. CUSANO, FELICE CARINI, Roberta |
Data pubblicazione: | 2018 | Rivista: | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY | Numero: | 473 | Fascicolo: | 2 | Da pagina:: | 2000 | Abstract: | We present the results of deep optical imaging of the radio/γ-ray pulsar PSR J2043+2740, obtained with the Large Binocular Telescope (LBT). With a characteristic age of 1.2 Myr, PSR J2043+2740 is one of the oldest (non-recycled) pulsars detected in γ-rays, although with still a quite high rotational energy reservoir (\dot{E}_rot = 5.6 × 10^{34} erg s<SUP>-1</SUP>). The presumably close distance (a few hundred pc), suggested by the hydrogen column density (N<SUB>H</SUB> ≲ 3.6 × 10<SUP>20</SUP> cm<SUP>-2</SUP>), would make it a viable target for deep optical observations, never attempted until now. We observed the pulsar with the Large Binocular Camera of the LBT. The only object (V = 25.44 ± 0.05) detected within ∼3 arcsec from the pulsar radio coordinates is unrelated to it. PSR J2043+2740 is, thus, undetected down to V ∼ 26.6 (3σ), the deepest limit on its optical emission. We discuss the implications of this result on the pulsar emission properties. | URI: | http://hdl.handle.net/20.500.12386/28240 | URL: | https://ui.adsabs.harvard.edu/link_gateway/2018MNRAS.473.2000T/arxiv:1709.09169 https://academic.oup.com/mnras/article/473/2/2000/4259589 |
