EK Cha b: multi-tracer detection of a protoplanet candidate in a gas-rich environment
Felipe Alarcón, C. Swastik, Stefano Facchini +2
Despite sustained community efforts and advances in instrumentation and high-contrast imaging, the search for protoplanets remains difficult, with only two widely accepted systems…
Oxygen Isotope Constraints on the Importance of Photochemical Processing in Protoplanetary Disks
Fred J. Ciesla, Eric Van Clepper, Jennifer Bergner +1
Observations have revealed evidence of photochemical processing in protoplanetary disks. This processing occurs in the photon dominated layer, the optically thin regions of the dis…
Dust Recycling and Icy Volatile Enhancement (DRIVE): A Novel Method of Volatile Enrichment in Cold Giant Planets
Eric R. Van Clepper, Felipe Alarcón, Edwin Bergin +1
Giant planet atmospheres are thought to reflect the gas phase composition of the disk when and where they formed. However, these atmospheres may also be polluted via solid accretio…
Direct Measurement of Extinction in a Planet-Hosting Gap
G. Cugno, S. Facchini, F. Alarcon +12
Recent disk observations have revealed multiple indirect signatures of forming gas giant planets, but high-contrast imaging has rarely confirmed the presence of the suspected pertu…
Burned to ashes: How the thermal decomposition of refractory organics in the inner protoplanetary disc impacts the gas-phase C/O ratio
Adrien Houge, Anders Johansen, Edwin Bergin +5
The largest reservoir of carbon in protoplanetary discs is stored in refractory organics, which thermally decompose into the gas-phase at the organics line, well interior to the wa…
Key Science Goals for the Next Generation Very Large Array (ngVLA): Update from the ngVLA Science Advisory Council (2024)
David J. Wilner, Brenda C. Matthews, Brett McGuire +32
In 2017, the next generation Very Large Array (ngVLA) Science Advisory Council, together with the international astronomy community, developed a set of five Key Science Goals (KSGs…
Thermal Structure and Millimeter Emission of Protoplanetary Disk with embedded protoplanets from radiative transfer modeling
Felipe Alarcón, Edwin Bergin
The discovery of protoplanets and circumplanetary disks provides a unique opportunity to characterize planet formation through observations. Massive protoplanets shape the physical…
Extinction values towards embedded planets in protoplanetary disks estimated from hydrodynamic simulations
Felipe Alarcón, Edwin Bergin, Gabriele Cugno
The upcoming new coronographs with deeper contrast limits, together with planned and current high-contrast imaging campaigns will push the detectability limit of protoplanets. Thes…
A far-ultraviolet-driven photoevaporation flow observed in a protoplanetary disk
Olivier Berné, Emilie Habart, Els Peeters +143
Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiati…
Tentative detection of cyanoformamide NCCONH2 in space
Juan Li, Donghui Quan, Junzhi Wang +12
The peptide-like molecules, cyanoformamide (NCCONH2), is the cyano (CN) derivative of formamide (NH2CHO). It is known to play a role in the synthesis of nucleic acid precursors und…
Mapping Observations of Peptide-like molecules around Sagittarius B2
Siqi Zheng, Juan Li, Junzhi Wang +7
Peptide-like molecule, which has a close connection with the origin of life, has been detected in universe. Mapping observations of HCONH and CHCONH, two simplest pepti…
MIRAC-5: A ground-based mid-IR instrumentwith the potential to detect ammonia in gas giants
R. Bowens, J. Leisenring, M. R. Meyer +12
We present the fifth incarnation of the Mid-Infrared Array Camera (MIRAC-5) instrument which will use a new GeoSnap (3 - 13 microns) detector. Advances in adaptive optics (AO) syst…
The physical and chemical structure of Sagittarius B2. II. Continuum millimeter emission of SgrB2(M) and SgrB2(N) with ALMA
A. Sanchez-Monge, P. Schilke, A. Schmiedeke +8
The high-mass star forming sites SgrB2(M) and SgrB2(N) have been the target of numerous studies, revealing e.g. a rich chemistry. We want to characterize their physical and chemica…
The physical and chemical structure of Sagittarius B2, I. Three-dimensional thermal dust and free-free continuum modeling on 100 au to 45 pc scales
A. Schmiedeke, P. Schilke, Th. Möller +8
We model the dust and free-free continuum emission in the high-mass star-forming region Sagittarius B2 in order to reconstruct the three-dimensional density and dust temperature di…
