Pristine ices in a planet-forming disk revealed by heavy water
Margot Leemker, John J. Tobin, Stefano Facchini +4
Water is essential to our understanding of the planet-formation process and habitability on Earth. Although trace amounts of water are seen across all phases of star and planet for…
Chemical abundance gradients of organic molecules within a protostellar disk
Levi G. Walls, Merel L. R. van 't Hoff, Edwin A. Bergin
Observations of low-mass protostellar systems show evidence of rich complex organic chemistry. Their low luminosity, however, makes determining abundance distributions of complex o…
Evidence for ubiquitous carbon grain destruction in hot protostellar envelopes
P. Nazari, B. Tabone, M. L. R. van 't Hoff +2
Earth is deficient in carbon and nitrogen by up to orders of magnitude compared with the Sun. Destruction of (carbon- and nitrogen-rich) refractory organics in the high-t…
A novel way of measuring the gas disk mass of protoplanetary disks using N2H+ and C18O
L. Trapman, K. Zhang, M. R. L. van 't Hoff +2
Measuring the gas mass of protoplanetary disks, the reservoir available for giant planet formation, has proven to be difficult. We currently lack a far-infrared observatory capable…
Molecules with ALMA at Planet-forming Scales (MAPS) XVII: Determining the 2D Thermal Structure of the HD 163296 Disk
Jenny K. Calahan, Edwin A. Bergin, Ke Zhang +26
Understanding the temperature structure of protoplanetary disks is key to interpreting observations, predicting the physical and chemical evolution of the disk, and modeling planet…
Molecules with ALMA at Planet-forming Scales (MAPS) V: CO gas distributions
Ke Zhang, Alice S. Booth, Charles J. Law +32
Here we present high resolution (15-24 au) observations of CO isotopologue lines from the Molecules with ALMA on Planet-forming Scales (MAPS) ALMA Large Program. Our analysis emplo…
