Rosette nebula globules: Seahorse giving birth to a star
M. M. Mäkelä, L. K. Haikala, G. F. Gahm
The Rosette Nebula is an HII region ionized mainly by the stellar cluster NGC 2244. Elephant trunks, globules, and globulettes are seen at the interface where the HII region and th…
Rosette Globulettes and Shells in the Infrared
M. M. Mäkelä, L. K. Haikala, G. F. Gahm
Tiny, dense clumps of sub-solar mass called globulettes form in giant galactic HII regions. The young central clusters compress the surrounding molecular shells which break up into…
Mass and motion of globulettes in the Rosette Nebula
Gösta F. Gahm, Carina M. Persson, Minja M. Mäkelä +1
We have investigated tiny molecular clumps in the Rosette Nebula. Radio observations were made of molecular line emission from 16 globulettes identified in a previous optical surve…
Star formation, structure, and formation mechanism of cometary globules: NIR observations of CG 1 and CG 2
M. M. Mäkelä, L. K. Haikala
Cometary globule (CG) 1 and CG 2 are "classic" CGs in the Gum Nebula. They have compact heads and long dusty tails that point away from the centre of the Gum Nebula. We study the s…
