Mazkur ishda sferik simmetriyaga ega bo‘lgan, zaryadlangan muntazam qora tuynuk — Sean A. Hayward tomonidan taklif etilgan model — ko‘rib chiqiladi. Ushbu model Albert Einstein tenglamalarining nochiziqli elektrodinamika bilan bog‘langan holatidagi Hans Reissner va Gunnar Nordström tomonidan ishlab chiqilgan klassik yechimning modifikatsiyasi hisoblanadi. Tadqiqot davomida qora tuynukning kritik massa qiymatlari hamda normallashtirish koeffitsiyenti aniqlanadi. Shuningdek, kvintessensiya maydoni bilan o‘ralgan Hayward qora tuynugida gorizontlarning tuzilishi va ekstremal holat sharti batafsil tahlil qilinadi.
Kvintessensiya holat parametri maxsus holda ω_q=-2/3 deb olinganda, samarali potensial funksiyaning xossalari o‘rganiladi. Bu orqali zarra harakatining barqarorlik shartlari va mumkin bo‘lgan orbitallarning xarakteri aniqlanadi. Ishda fazo-vaqt geometriyasining muhim invariant kattaliklari, jumladan skalyar invariantlar, shuningdek eng ichki barqaror aylana orbitaning (ISCO) radiusi tahlil qilinadi. Bundan tashqari, Hayward qora tuynugi atrofida sinov zarralarining dinamik harakati chuqur o‘rganiladi.
