Over the past decade, many rapidly evolving optical transients (REOTs), whose
rise and decline timescales are significantly shorter than those of canonical
supernovae (SNe), have been discovered and studied. Some REOTs have high peak
luminosity ($gtrsim 10^{43}$ erg s$^{-1}$), disfavoring the
radioactivity-powered-SN model that has been widely adopted to explain normal
SNe. In this paper, we study three luminous REOTs (PS1-10bjp, PS1-11bbq, and
PS1-13ess) and use a model involving magnetar energy input to fit their
bolometric light curves and temperature evolution. We find that core-collapse
SNe (CCSNe) powered by magnetars with $P_0 approx 18$–34 ms and $B_p approx$
(2.5–5.8) $times10^{15}$ G can reproduce their bolometric light curves as
well as the temperature evolution. The inferred values of ejecta mass are $sim
0.40$–0.46 M$_odot$, slightly smaller than that of the Type Ic SN 1994I,
indicating that they can be explained by the magnetar-powered stripped CCSN
model.
