| 英文摘要 | The short GRB 190610A (Swift-BAT detection: Evans et al., GCN 24775; Insight-HXMT/HE detection: Cai et al., GCN 24782) triggered Konus-Wind (KW) at T0=41263.560 s UT (11:27:43.560). The light curve of the burst shows a single, multi-peaked pulse with a total duration of ~0.6 s. The emission is seen up to ~10 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB190610_T41263/ As observed by Konus-Wind, the burst had a fluence of (7.65 ± 1.48)x10^-6 erg/cm^2 and a 16-ms peak energy flux, measured from T0+0.080, of (2.43 ± 0.31)x10^-5 erg/cm^2/s (both in the 20 keV - 10 MeV energy range). The spectrum of the burst (measured from T0 to T0+0.256 s) is well fitted in the 20 keV - 20 MeV range by a cutoff power-law (CPL) function with the following model parameters: the photon index alpha = -0.28(-0.26,+0.33), and the peak energy Ep = 903(-181,+251) keV, chi2 = 53/47 dof. Fitting this spectrum with the GRB (Band) function yields nearly the same alpha and Ep, and an upper limit on beta of -2.3. All the quoted errors are estimated at the 90% confidence level. All the presented results are preliminary. |
