ALMAGAL VIII. Early phases of triggered star formation in source AG286.07161.8229
C. Mininni, S. Molinari, W. J. Kim +50
Several theoretical and observational studies have shown that new waves of triggered star-formation can be induced by the feedback from newly formed massive protostars, due to the…

Gravitational trapping and ram pressure trapping of ultracompact and hypercompact H II regions
Lauren Martini, André Oliva, Rolf Kuiper +1
Observationally, early H II regions are classified by size into ultracompact and hypercompact configurations. It remains unclear whether these phases are long-lived or transient. U…

Gas infall via accretion disk feeding Cepheus A HW2
A. Sanna, A. Oliva, L. Moscadelli +10
The star-forming region Cepheus A hosts a very young star, called HW2, that is the second closest to us growing a dozen times more massive than our Sun. The circumstellar environme…
