Evidence for triggered star formation linking three generations of stars is difficult to assemble, as it requires convincingly associating evolved massive stars with H ii regions that, in turn, would need to present signs of active star formation. We present observational evidence for triggered star formation relating three generations of stars in the neighbourhood of the star LS II +26 8. We carried out new spectroscopic observations of LS II +26 8, revealing that it is a B0 III-type star… Expand

Hierarchical Triggering of Star Formation by Superbubbles in W3/W4
It is generally believed that expanding superbubbles and mechanical feedback from massive stars trigger star formation, because there are numerous examples of superbubbles showing secondary starExpand
Triggered star formation on the borders of the Galactic Hii region RCW 82
Context. We are engaged in a multi-wavelength study of several Galactic Hii regions that exhibit signposts of triggered star formation on their borders, where the collect and collapse process couldExpand
Active Star Formation in the N11B Nebula in the Large Magellanic Cloud: A Sequential Star Formation Scenario Confirmed* **
The second largest H ii region in the Large Magellanic Cloud, N11B has been surveyed in the near-IR. We present JHKs images of the N11B nebula. These images are combined with CO (1 ! 0) emission-lineExpand
Star formation triggered by H II regions in our Galaxy First results for N49 from the Herschel infrared survey of the Galactic plane
Context. It has been shown that by means of different physical mechanisms the expansion of H II regions can trigger the formation of new stars of all masses. This process may be important to theExpand
The stellar content of LH 9 and 10 (N11) in the LMC - A case for sequential star formation
The young OB associations Lucke-Hodge 9 and 10 are studied with UBV photometry that is independent of reddening to determine the IMF directly from star counts. The temperature and reddening of theExpand
The molecular complex associated with the Galactic H II region Sh2-90: a possible site of triggered star formation
Aims. We investigate the star formation activity in the molecular complex associated with the Galactic H II region Sh2-90. Methods. We obtain the distribution of the ionized and cold neutral gasExpand
Supernova Remnants in Molecular Clouds
Massive (8 M☉) stars may end their lives in the molecular clouds in which they were born. O-type stars probably have sufficient photoionizing radiation and wind power to clear a region more than 15Expand
LINEAR RELATION FOR WIND-BLOWN BUBBLE SIZES OF MAIN-SEQUENCE OB STARS IN A MOLECULAR ENVIRONMENT AND IMPLICATION FOR SUPERNOVA PROGENITORS
We find a linear relationship between the size of a massive star's main-sequence bubble in a molecular environment and the star's initial mass: R{sub b} Almost-Equal-To 1.22 M/M{sub Sun} - 9.16 pc,Expand
Masses and luminosities of O- and B-type stars and red supergiants
Massive stars are of interest as progenitors of supernovae, i.e. neutron stars and black holes, which can be sources of gravitational waves. Recent population synthesis models can predict neutronExpand
