by Using the Gemini Multi-conjugate Adaptive Optics System (GeMS) and the Gemini South Adaptive Optics Imager (GSAOI) on the 8.1-m Gemini South telescope on Cerro Pachón on the edge of the Chilean Andes, astronomers have captured images of two wiggling stellar jets: MHO 2147 and MHO 1502.
“Stellar jets and molecular outflows are ubiquitous in star-forming regions to such an extent that they are considered to be signposts of newly formed stars,” said lead author Dr. Leticia Ferrero, an astronomer at the Universidad Nacional de Córdoba and CONICET and her colleagues.
“Furthermore, they are usually associated with the earliest stages of stellar formation, when the incipient proto-stellar object is deeply embedded within a dense core of dust and molecular gas.”
“In the optical and near-infrared ranges, jets usually consist of a chain of knots with a terminal leading bow shock emanating from the young star and propagating away at high supersonic speeds.”
“Although most jets are straight or collimated, others have curved shapes.”
