ALMA unveils rings and gaps in the protoplanetary system HD 169142: signatures of two giant protoplanets
Davide Fedele,M. T. Carney,Michiel R. Hogerheijde,Catherine Walsh,Catherine Walsh,Anna Miotello,Pamela Klaassen,Simon Bruderer,Th. Henning,E. F. van Dishoeck +9 more
TL;DR: In this paper, the authors used ALMA observations of the dust continuum at 1.3 mm, 12 CO, 13 CO, and C18 O J = 2−1 emission from the system HD 169142 (which is observed almost face-on) at an angular resolution of ~ 35 × 20 au, revealing a double-ring structure with an inner ring between 20−35 au and an outer ring between 56−83 au.

TL;DR: In this article, the authors used the IRAM Northern Extended Millimeter Array (NOEMA) in combination with the 30m telescope to detect 1.37mm continuum and spectral line emission at high angular resolution (~0.4'') for a sample of 20 well-known high-mass star-forming regions with distances below 5.5kpc and luminosities larger than 10^4Lsun.
