Hot methanol in the [BHB2007] 11 protobinary system: hot corino versus shock origin? : FAUST V
C. Vastel, F. Alves, C. Ceccarelli +63
Methanol is a ubiquitous species commonly found in the molecular interstellar medium. It is also a crucial seed species for the building-up of the chemical complexity in star formi…
An infrared measurement of chemical desorption from interstellar ice analogues
Y. Oba, T. Tomaru, T. Lamberts +2
In molecular clouds at temperatures as low as 10 K, all species except hydrogen and helium should be locked in the heterogeneous ice on dust grain surfaces. Nevertheless, astronomi…
FAUST I. The hot corino at the heart of the prototypical Class I protostar L1551 IRS5
E. Bianchi, C. J. Chandler, C. Ceccarelli +63
The study of hot corinos in Solar-like protostars has been so far mostly limited to the Class 0 phase, hampering our understanding of their origin and evolution. In addition, recen…
Efficient formation pathway of methyl formate: the role of OH radicals on ice dust
A. Ishibashi, H. Hidaka, Y. Oba +2
Three structural isomers of the C2H4O2 molecule, namely, methyl formate (MF; HCOOCH3), acetic acid (AA; CH3COOH), and glycol aldehyde (GA; HOCH2CHO), have attracted considerable at…
FAUST XIII. Dusty cavity and molecular shock driven by IRS7B in the Corona Australis cluster
G. Sabatini, L. Podio, C. Codella +54
The origin of the chemical diversity observed around low-mass protostars probably resides in the earliest history of these systems. We aim to investigate the impact of protostellar…
Small-angle neutron scattering by spatially inhomogeneous ferromagnets with a nonzero average uniaxial anisotropy
V. D. Zaporozhets, Y. Oba, A. Michels +1
Micromagnetic small-angle neutron scattering theory is well established for analyzing spin-misalignment scattering data of bulk ferromagnets. Here, this theory is extended to allow…
FAUST XVII: Super deuteration in the planet forming system IRS 63 where the streamer strikes the disk
L. Podio, C. Ceccarelli, C. Codella +55
Recent observations suggest that planets formation starts early, in protostellar disks of yrs, which are characterized by strong interactions with the environment, e.g.,…
FAUST XXXI. Grain properties and variability of three sources in GSS 30
Q. Yang, H. Baobab Liu, S. Feng +55
To advance our understanding of dust properties in class 0/I young stellar objects, it is crucial to resolve their structures at multiple wavelengths and investigate how grain grow…
Water Formation through a Quantum Tunneling Surface Reaction, OH + H2, at 10 K
Y. Oba, N. Watanabe, T. Hama +3
The present study experimentally demonstrated that solid H2O is formed through the surface reaction OH + H2 at 10 K. This is the first experimental evidence of solid H2O formation…
