Young Stellar Object Candidates in IC 417
The Astronomical Journal, 2023 IC 417 is in the Galactic plane, and likely part of the Aur OB2 association; it is ∼2 kpc away. Stock 8 is one of the densest cluster constituents; off of it to the east, there is a “nebulous stream” (NS) that is dramatic in the infrared (IR).

HH 80/81: Structure and Kinematics of the Fastest Protostellar Outflow
The Astrophysical Journal, 2023 Hubble Space Telescope (HST) images obtained in 2018 are combined with archival HST data taken in 1995 to detect changes and measure proper motions in the HH 80/81 shock complex, which is powered by the fastest known jet driven by a forming star, the ...

On the Formation of Massive Stars [PDF]
The Astrophysical Journal, 2002 We calculate numerically the collapse of slowly rotating, non-magnetic, massive molecular clumps, which conceivably could lead to the formation of massive stars. Because radiative acceleration on dust grains plays a critical role in the clump's dynamical evolution, we utilize a wavelength-dependent radiation transfer and a three component dust model ...

The Astrophysical Journal Letters, 2023 Cylindrical molecular filaments are observed to be the main sites of Sunlike star formation, while massive stars form in dense hubs at the junction of multiple filaments.

International Astronomical Union Colloquium, 1989 Judging from the poster that the Organizing Committee has selected to announce the celebration of Guido Munch Jubilee, one can easily conclude that the main characteristics of the process of star formation as emerged in recent years through the combined efforts of multiwavelengths studies of molecular clouds, were already known, here in Granada ...

On the formation of massive stars [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We present a model for the formation of massive ($M > 10 M_\odot$) stars through accretion-induced collisions in the cores of embedded dense stellar clusters. This model circumvents the problem of accreting onto a star whose luminosity is sufficient to reverse the infall of gas.

The Astrophysical Journal, 2023 A variety of interstellar complex organic molecules (COMs) have been detected in various physical conditions. However, in the protostellar and protoplanetary environments, their complex kinematics make line profiles blend together and the line strength ...

Membership Analysis and 3D Kinematics of the Star-forming Complex around Trumpler 37 Using Gaia-DR3
The Astrophysical Journal, 2023 Identifying and characterizing young populations of star-forming regions are crucial to unraveling their properties. In this regard, Gaia-DR3 data and machine-learning tools are very useful for studying large star-forming complexes.

Complex Organic Molecules in a Very Young Hot Corino, HOPS 373SW
The Astrophysical Journal, 2023 We present the spectra of complex organic molecules (COMs) detected in HOPS 373SW with the Atacama Large Millimeter/submillimeter Array (ALMA). HOPS 373SW, which is a component of a protostellar binary with a separation of 1500au, has been discovered as ...
