Sporadic Dips from Extended Debris Transiting the Metal-rich White Dwarf SBSS 1232+563

Sporadic Dips from Extended Debris Transiting the Metal-rich White Dwarf SBSS 1232+563

We present the discovery of deep but sporadic transits in the flux of SBSS 1232+563, a metal-rich white dwarf polluted by disrupted exoplanetary debris. Nearly 25 yr of photometry from multiple sky surveys reveal evidence of occasional dimming of the white dwarf, most notably evident in an 8 month l...
