A possible answer to the challenge brought by the construction of the next generation 40 m-class telescopes was the case study of FAME (Freeform Active Mirror...

We study photometric variable stars in two open clusters of very different age: σ Orionis (τ ˜ 3 Ma, d ˜ 385 pc) and NGC 6811 (τ ˜ 600 Ma, d ˜ 1000 pc). In NGC...
