IN his communication in NATURE1 on non-solar planetary systems, Sir James Jeans writes, ``Mr. Sen refers with approval to Banerji's modification of this [tidal] theory. This makes the original sun a Cepheid which had its oscillatory instability increased by the gravitational attraction of a passing star. But a passing star cannot increase the instability of a Cepheid appreciably unless it comes very near. ... Judging from their luminosity, all Cepheids are much more massive than the sun or 61 Cygni or 70 Ophiuchi''.
