Yasuhiro Hasegawa, 2021, "Z CMa: A Likely Flyby Event Caught in Action", https://doi.org/10.48577/jpl.YPJ3DI, nature astronomy, JPL Open Repository
Close encounters between young stellar objects in star forming clusters are expected to dramatically perturb circumstellar disks. Such events are witnessed in numerical simulations of star formation1–3,but few direct observations of ongoing encounters have been made. Here we repo... |

Connor, Thomas P, 2021, "X-Ray Evidence Against the Hypothesis that the Hyper-Luminous z = 6:3 Quasar J0100+2802 is Lensed", https://doi.org/10.48577/jpl.DDQRHQ, The Astrophysical Journal Letters, JPL Open Repository
The z = 6:327 quasar SDSS J010013.02+280225.8 (hereafter J0100+2802) is believed to be powered by ablack hole more massive than 1010 M , making it the most massive black hole known in the first billion yearsof the Universe. However, recent high-resolution ALMA imaging shows four... |

Mark Panning, 2021, "Wind and Surface Roughness Considerations for Seismic Instrumentation on a Relocatable Lander for Titan", https://doi.org/10.48577/jpl.NSHLW7, Planetary and Space Science, JPL Open Repository
The influence of terrain and the atmosphere on seismic measurements to be made by the Dragonfly rotorcraft lander on Saturn’s moon Titan are examined. The need to relocate the vehicle leads to rather different deployment considerations from a fixed lander. Surface texture affects... |

Sholes, Steven F, 2021, "Where are Mars’ Hypothesized Ocean Shorelines? Large Lateral and Topographic Offsets Between Different Versions of Paleoshoreline Maps.", https://doi.org/10.48577/jpl.CYRSLM, Journal of Geophysical Research: Planets, JPL Open Repository
Mars’ controversial hypothesized ocean shorelines have been found to deviate significantly from an expected equipotential surface. While multiple deformation models have been proposed to explain the wide range of elevations, here we show that the historical locations used in the... |

Alexander Handwerger, 2021, "When image correlation is needed: unravelling the complex dynamics of a slow-moving landslide in the tropics with dense radar and optical time series.", https://doi.org/10.48577/jpl.WKFAW1, Remote Sensing of Environment, JPL Open Repository
Slow-moving landslides exhibit persistent but non-uniform motion at low rates which makes them25 exceptional natural laboratories to study the mechanisms that control the dynamics of unstable26 hillslopes. Here we leverage 4.5+ years of satellite-based radar and optical remote se... |

Andreas Colliander, 2021, "Wave Propagation in Vegetation Field Using a Hybrid Method", https://doi.org/10.48577/jpl.Y2DMC6, Transactions on Antennas and Propagation, JPL Open Repository
In this paper, we develop a hybrid method for studying wave scatterings and propagation in a vegetation field. The coherent multiple scatterings among the plants and the gaps in the vegetation field are considered through a two-step hybrid method. First, the T-matrix of a single... |

Dariusz Lis, 2021, "Water in star-forming regions: physics and chemistry from clouds to disks as probed by Herschel spectroscopy", https://doi.org/10.48577/jpl.B0KIHG, Astronomy & Astrophysics, JPL Open Repository
Context. Water is a key molecule in the physics and chemistry of star and planet formation, but is difficult to observe from Earth. The Herschel Space Observatory provided unprecedented sensitivity, spatial and spectral resolution to study water. The ‘Water In Star-forming region... |

Hanii Takahashi, 2021, "Warm Cloud Evolution, Precipitation, and Their Weak Linkage in HadGEM3: New Process-Level Diagnostics using A-Train Observations", https://doi.org/10.48577/jpl.69SYXS, JAS, JPL Open Repository
The latest configuration of the Hadley Centre Global Environmental Model version 3 (HadGEM3) contains significant changes in the formulation of warm rain processes and aerosols. We evaluate the impacts of these changes in the simulation of warm rain formation processes using A-Tr... |

Scott, David C, 2021, "Voyager 3: A Concept Mission to Interstellar Medium", https://doi.org/10.48577/jpl.QLGF8V, AIAA Journal of Spacecraft and Rockets, JPL Open Repository
The Voyager 3 is a concept mission that sends a space telescope to the interstellar medium in a reasonable amount of time. Voyager 3 will take a direct image of an exoplanet using the solar gravitational lensing at the distance of 550 AU. The spacecraft will use its suite of scie... |

Apurva Oza, 2021, "Volatile Transport Modeling on Triton with New Observational Constraints", https://doi.org/10.48577/jpl.4WWMXC, Icarus, JPL Open Repository
Neptune’s moon Triton shares many similarities with Pluto, including volatile cycles of N2, CH4and CO, and represents a benchmark case for the study of surface-atmosphere interactions onvolatile-rich Kuiper Belt objects. The observations of Pluto by New Horizons acquired during t... |
