A finding chart for V515 And

SkyView image of V515 And (see important notes).

Position
  • Equatorial: 00h55m19.85s, +46d12m56.9s (Gaia)
  • Galactic: l= 123.63, b=-16.65
Finding Chart:
Bikmaev et al. (2006)
Brigntness:
Optical: G=14.8 (Gaia); X-rays: 1.9x10-11 ergs cm-2s-1 (BAT 157m; 14-195 keV), 2.6x10-11 ergs cm-2s-1 (4XMM-DR11)
IP Credential:
**** (Confirmed): The spin period is well-established through X-ray and optical observations. The orbital period is mainly infered from the spin and beat period (also seen in optical photometry), without precise determination from optical spectroscopy.
Periods:
  • Orbital: 0.1137953 d = 2.731087 hr = 9831.914 s (inferred)
  • Spin: 0.0053875571 d = 7.7580822 min = 465.48493 s, seen in X-ray and optical photometry.
    BJD(max) = 2454743.146425 (23) + 0.0053875571 (8) E
    (Kozhevnikov 2012) from optical photometry, also seen in X-rays (465.68 s with RXTE; the 469.75s period seen with XMM-Newton is likely to be a blend of this and the beat period)
  • Others: 0.005655303 d = 8.143637 min = 488.61822 s
    BJD(max) = 2454743.150323 (20) + 0.0056553035 (10) E
    (Kozhevnikov 2012) from optical photometry.
Inclination:
?
Distance:
930.1 (910.2-946.7) pc (Gaia EDR3; parallax: 1.044+/-0.025 mas)
