- W4282839035 abstract "Cool stars on the main sequence generate X-rays from coronal activity, powered by a convective dynamo. With increasing temperature, the convective envelope becomes smaller and X-ray emission fainter. We present Chandra/HRC-I observations of four single stars with early A spectral types. Only the coolest star of this sample, $tau^3$ Eri ($T_mathrm{eff}approx8,,000$ K), is detected with $log(L_X/L_mathrm{bol})=-7.6$ while the three hotter stars ($T_mathrm{eff}geq8,,000$ K), namely $delta$ Leo, $beta$ Leo, and $iota$ Cen, remain undetected with upper limits $log(L_X/L_mathrm{bol})<-8.4$. The drop in X-ray emission thus occurs in a narrow range of effective temperatures around $sim 8100$ K and matches the drop of activity in the C III and O VI transition region lines." @default.
