FAUST XXVI. The dust opacity spectral indices of protostellar envelopes bridge the gap between interstellar medium and disks

Luca Cacciapuoti, L. Testi, A. J. Maury +36

The sub-millimetre dust opacity spectral index is a critical observable to constrain dust properties, such as the maximum grain size of an observed dust population. It has been wid…

FAUST XX. The chemical structure and temperature profile of the IRAS 4A2 hot corino at 20-50 au

J. Frediani, M. De Simone, L. Testi +20

Young low-mass protostars often possess hot corinos, compact, hot and dense regions bright in interstellar Complex Organic Molecules (iCOMs). Besides of their prebiotic role, iCOMs…

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 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…

FAUST IX. Multi-band, multi-scale dust study of L1527 IRS. Evidence for dust properties variations within the envelope of a Class 0/I YSO

L. Cacciapuoti, E. Macias, A. J. Maury +25

Early dust grain growth in protostellar envelopes infalling on young discs has been suggested in recent studies, supporting the hypothesis that dust particles start to agglomerate…

Confronting Cosmology and New Physics with Fundamental Constants

Rodger I. Thompson

The values of the fundamental constants such as , the proton to electron mass ratio and , the fine structure constant, are sensitive to the product $\sqrt{ζ_x^2(w+1)…

An Observational Determination of the Proton to Electron Mass Ratio in the Early Universe

Rodger I. Thompson, Jill Bechtold, John H. Black +6

In an effort to resolve the discrepancy between two measurements of the fundamental constant mu, the proton to electron mass ratio, at early times in the universe we reanalyze the…
