Classic 2 transistor astable multivibrator with collector catch diodes using PNP emitter followers to increase rise time. Q6, Q7, Q8 provide temperature compensation. Q5 offsets the Vbe drop including temperature drift of Q3 The unequal base resistors help it start up asymmetrically.
Temperature stabilization based on:

Use of LIMIT expression in V1 to ramp up the supply slightly reduces the simulation time too.
