Deprojecting and constraining the vertical thickness of exoKuiper belts
James Terrill, Sebastian Marino, Richard A. Booth +3
Constraining the vertical and radial structure of debris discs is crucial to understanding their formation, evolution and dynamics. To measure both the radial and vertical structur…
Regularized Maximum Likelihood Image Synthesis and Validation for ALMA Continuum Observations of Protoplanetary Disks
Brianna Zawadzki, Ian Czekala, Ryan A. Loomis +6
Regularized Maximum Likelihood (RML) techniques are a class of image synthesis methods that achieve better angular resolution and image fidelity than traditional methods like CLEAN…
Distribution of solids in the rings of the HD 163296 disk: a multiwavelength study
G. Guidi, A. Isella, L. Testi +15
In this paper we analyze new observations from ALMA and VLA, at a high angular resolution corresponding to 5 - 8 au, of the protoplanetary disk around HD 163296 to determine the du…
Super-resolution trends in the ALMA Taurus survey: Structured inner discs and compact discs
Jeff Jennings, Marco Tazzari, Cathie J. Clarke +2
The 1.33 mm survey of protoplanetary discs in the Taurus molecular cloud found annular gaps and rings to be common in extended sources (>~55 au), when their 1D visibility distribut…
Unveiling the outer dust disc of TW Hya with deep ALMA observations
John D. Ilee, Catherine Walsh, Jeff Jennings +5
The radial extent of millimetre dust in protoplanetary discs is often far smaller than that of their gas, mostly due to processes such as dust growth and radial drift. However, it…
Broadband stability of the Habitable Zone Planet Finder Fabry-Pérot etalon calibration system: evidence for chromatic variation
Ryan C Terrien, Joe P Ninan, Scott A Diddams +11
The comb-like spectrum of a white light-illuminated Fabry-Pérot etalon can serve as a cost-effective and stable reference for precise Doppler measurements. Understanding the stabil…
A super-resolution analysis of the DSHARP survey: Substructure is common in the inner 30 au
Jeff Jennings, Richard A. Booth, Marco Tazzari +2
The DSHARP survey evidenced the ubiquity of substructure in the mm dust distribution of large, bright protoplanetary discs. Intriguingly, these datasets have yet higher resolution…
Dual-Wavelength ALMA Observations of Dust Rings in Protoplanetary Disks
Feng Long, Paola Pinilla, Gregory J. Herczeg +13
We present new Atacama Large Millimeter/submillimeter Array (ALMA) observations for three protoplanetary disks in Taurus at 2.9\,mm and comparisons with previous 1.3\,mm data both…
Frankenstein: Protoplanetary disc brightness profile reconstruction at sub-beam resolution with a rapid Gaussian process
Jeff Jennings, Richard A. Booth, Marco Tazzari +2
Interferometric observations of the mm dust distribution in protoplanetary discs are now showing a ubiquity of annular gap and ring substructures. Their identification and accurate…
Frequency stability of the mode spectrum of broad bandwidth Fabry-Perot interferometers
Jeff Jennings, Ryan Terrien, Connor Fredrick +5
When illuminated by a white light source, the discrete resonances of a Fabry-Perot interferometer (FP) provide a broad bandwidth, comb-like spectrum useful for frequency calibratio…
Modelling thermochemical processes in protoplanetary disks I: numerical methods
T. Grassi, B. Ercolano, L. Szűcs +2
The dispersal phase of planet-forming disks via winds driven by irradiation from the central star and/or magnetic fields in the disk itself is likely to play an important role in t…
A sub-Neptune sized planet transiting the M2.5-dwarf G 9-40: Validation with the Habitable-zone Planet Finder
Gudmundur Stefansson, Caleb Cañas, John Wisniewski +32
We validate the discovery of a 2 Earth radii sub-Neptune-size planet around the nearby high proper motion M2.5-dwarf G 9-40 (EPIC 212048748), using high-precision near-infrared (NI…
Evidence for He I 10830 Å~ absorption during the transit of a warm Neptune around the M-dwarf GJ 3470 with the Habitable-zone Planet Finder
Joe P. Ninan, Gudmundur Stefansson, Suvrath Mahadevan +21
Understanding the dynamics and kinematics of out-flowing atmospheres of hot and warm exoplanets is crucial to understanding the origins and evolutionary history of the exoplanets n…
Stellar Spectroscopy in the Near-infrared with a Laser Frequency Comb
Andrew J. Metcalf, Tyler Anderson, Chad F. Bender +34
The discovery and characterization of exoplanets around nearby stars is driven by profound scientific questions about the uniqueness of Earth and our Solar System, and the conditio…
The comparative effect of FUV, EUV and X-ray disc photoevaporation on gas giant separations
Jeff Jennings, Barbara Ercolano, Giovanni P. Rosotti
Gas giants' early ( Myr) orbital evolution occurs in a disc losing mass in part to photoevaporation driven by high energy irradiance from the host star. This process ma…
X-ray photoevaporation's limited success in the formation of planetesimals by the streaming instability
Barbara Ercolano, Jeff Jennings, Giovanni Rosotti +1
The streaming instability is often invoked as solution to the fragmentation and drift barriers in planetesimal formation, catalyzing the aggregation of dust on kyr timescales to gr…
