“…These temperatures are significantly higher than those obtained for the hot component in our analysis. Part of this discrepancy might be explained by the different sensitivity of the instruments, due to the different spectral band, that would lead the instruments to be sensitive to different parts a broad emission measure distribution (Peres et al 2000;Hannah et al 2011). The average emission measure obtained from thermal fitting of RHESSI microflares is about 2−3 × 10 46 cm −3 , which is much larger than the emission measure of the hot components that we obtain.…”

“…The intrinsic quiescent X-ray luminosity in LkHα 312 is 6 × 10 30 erg s −1 in the Chandra band (0.5-8 keV) and probably ∼10 31 erg s −1 in a full bolometric X-ray band. In contrast, the bolometric X-ray luminosity of the non-flaring solar corona is only 3 × 10 27 erg s −1 during solar minimum to 3 × 10 28 erg s −1 during solar maximum (Peres et al 2000). Note that the surface area of LkHα 312 is only 6.8 times that of the Sun (see Sect.…”

“…5.2.1, Table 4). In contrast, the non-flaring solar corona has average (weighted over the emission measure) temperature of ∼2 MK (Peres et al 2000). The intrinsic quiescent X-ray luminosity in LkHα 312 is 6 × 10 30 erg s −1 in the Chandra band (0.5-8 keV) and probably ∼10 31 erg s −1 in a full bolometric X-ray band.…”

“…7 shows a comparison of its EMD distribution vs. temperature (Method 1) with those of other four G-K stars: the Sun (G2V, Peres et al 2000), κ 1 Ceti (G5V, Telleschi et al 2005), Eri (K2V, Sanz-Forcada et al 2004), andHD 283572 (G2IV, Scelsi et al 2005).…”
