A new oscillation pattern in three-flavor normal quark matter satisfying these conditions is found and its bulk viscosity is calculated. The result may have astrophysical implication for maximum rotation frequencies of compact stars.ReVTex 4, 5 pages, 3 figures; some comments added; accepted version to PRDAstrophysicsHigh Energy Physics - PhenomenologyNuclear Theorytext
