Table 1:

The four radiation components of our T Tauri model star.
		(1)	(2)	(3)	(4)
i	component	L/L_*	spectrum	$h\overline{\nu}_{\rm em}$	F₁₀
				(eV)	(erg s^-1cm^-2)
1	photosphere	0.99	4000 K BB	0.9	30 000
2	FUV	0.01	15 000 K BB	3.5	300
3	EUV	0.001	$3\times 10^5$ K BB	70	30
4	X-rays ( $h\nu < 2$ keV)	$2.5\times 10^{-4}$	$\propto$ $\nu^2$	1330	10

Notes. (1) fractional luminosity; (2) spectral shape (BB = blackbody); (3) mean energy of emitted photons, $h\overline{\nu}_{\rm em}$ ; (4) approximate flux at 10 AU, F₁₀.
