Does TV Col have the longest recorded positive superhumps?
- Re-examination of extensive photometric data of TV Col reveals evidence for a permanent positive superhump. Its period (6.4 hr) is 16 percent longer than the orbital period and obeys the well known relation between superhump period excess and binary period. At 5.5-hr, TV Col has an orbital period longer than any known superhumping cataclysmic variable and, therefore, a mass ratio which might be outside the range at which superhumps can occur according to the current theory. We suggest several solutions for this problem.
