Molecules with ALMA at Planet-forming Scales (MAPS) XIII: HCO and disk ionization structure

Yuri Aikawa, Gianni Cataldi, Yoshihide Yamato +25

We observed HCO and HCO emission towards the five protoplanetary disks around IM Lup, GM Aur, AS 209, HD 163296, and MWC 480 as part of the MAPS proj…

Molecules with ALMA at Planet-forming Scales (MAPS) XI: CN and HCN as Tracers of Photochemistry in Disks

Jennifer B. Bergner, Karin I. Oberg, Viviana V. Guzman +23

UV photochemistry in the surface layers of protoplanetary disks dramatically alters their composition relative to previous stages of star formation. The abundance ratio CN/HCN has…

An unbiased NOEMA 2.6 to 4 mm survey of the GG Tau ring: First detection of CCS in a protoplanetary disk

N. T. Phuong, A. Dutrey, E. Chapillon +13

Molecular line surveys are among the main tools to probe the structure and physical conditions in protoplanetary disks (PPDs), the birthplace of planets. The large radial and verti…

Molecules with ALMA at Planet-forming Scales (MAPS). X. Studying deuteration at high angular resolution toward protoplanetary disks

Gianni Cataldi, Yoshihide Yamato, Yuri Aikawa +26

Deuterium fractionation is dependent on various physical and chemical parameters. Thus, the formation location and thermal history of material in the solar system is often studied…

Massive compact disks around FU Orionis-type young eruptive stars revealed by ALMA

Á. Kóspál, F. Cruz-Sáenz de Miera, J. A. White +14

FU Orionis-type objects (FUors) are low-mass pre-main sequence stars undergoing a temporary, but significant increase of mass accretion rate from the circumstellar disk onto the pr…

The first radio spectrum of a rapidly rotating A-type star

Jacob Aaron White, F. Tapia-Vázquez, A. G. Hughes +9

The radio spectra of main-sequence stars remain largely unconstrained due to the lack of observational data to inform stellar atmosphere models. As such, the dominant emission mech…
