Neal Turner, 2020, "X-Ray Ionization of Planet-Opened Gaps in Protostellar Disks", https://doi.org/10.48577/jpl.KBLXW7, Astrophysical Journal, JPL Open Repository
Young planets with masses approaching Jupiter's have tides strong enough to clear gaps around their orbits in the protostellar disk. Gas ow through the gaps regulates the planets' further growth and governs the disks' evolution. Magnetic forces may drive that ow if the gas is su... |

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... |

Sahai, Raghvendra; Kastner, Joel H.; Frank, Adam; Morris, Mark; Blackman, Eric G., 2003, "X-ray emission from the pre–planetary Nebula Henize 3-1475", https://hdl.handle.net/2014/40954, The Astrophysical Journal Letters, 599:L87–L90, 2003 December 20, JPL Open Repository
We report the first detection of X-ray emission in a pre–planetary nebula, He 3-1475. Pre–planetary nebulae are rare objects in the short transition stage between the asymptotic giant branch (AGB) and planetary nebula evolutionary phases, and He 3-1475, characterized by a remarka... |

Eric Mamajek, 2020, "WISEA J041451.67−585456.7 and WISEA J181006.18−101000.5: The First Extreme T-type Subdwarfs?", https://doi.org/10.48577/jpl.1F8VDN, The Astrophysical Journal Letters, JPL Open Repository
We present the discovery of WISEA J041451.67−585456.7 and WISEA J181006.18−101000.5, two low-temperature (1200-1400 K), high proper motion T-type subdwarfs. Both objects were discovered via their high proper motion (>0.5′′yr−1) and confirmed as brown dwarfs with follow-up near-in... |

Jonathan Jiang, 2020, "Wintertime particulate matter decrease buffered by unfavorable chemical processes despite emission reductions in China", https://doi.org/10.48577/jpl.LSS0I9, Geophysical Research Letters, JPL Open Repository
Extreme and persistent haze events frequently occur during wintertime China. While recent emissions reductions reduced annual mean fine particulate matter (PM2.5) concentrations over eastern China, their effectiveness on wintertime PM2.5 trend remains uncertain. We use observatio... |

Bridges, N. T.; Geissler, P. E.; McEwen, A. S.; Thomson, B. J.; Chuang, F. C.; Herkenhoff, K. E.; Keszthelyi, L. P.; Martınez-Alonso, S., 2007, "Windy Mars : A dynamic planet as seen by the HiRISE camera", https://hdl.handle.net/2014/40888, Geophysical Research Letters, Vol. 34, L23205, doi:10.1029/2007GL031445, 2007, JPL Open Repository
With a dynamic atmosphere and a large supply of particulate material, the surface of Mars is heavily influenced by wind-driven, or aeolian, processes. The High Resolution Imaging Science Experiment (HiRISE) camera on the Mars Reconnaissance Orbiter (MRO) provides a new view of Ma... |

Waliser, Duane E, 2020, "Windows of Opportunity for Skillful Forecasts Subseasonal to Seasonal and Beyond", https://doi.org/10.48577/jpl.EUWQCL, Bulletin of American Meteorological Society, JPL Open Repository
There is high demand and a growing expectation for predictions of environmental conditions that go beyond 0-14 day weather forecasts with outlooks extending to one or more seasons and beyond. This is driven by the needs of the energy, water management, and agriculture sectors, to... |

Torres Gutierrez, Hector, 2022, "Wind work at the air-sea interface: A Modeling Study in Anticipation of Future Space Missions", https://doi.org/10.48577/jpl.HBFHAB, Geoscientific Model Development, JPL Open Repository
Wind work at the air-sea interface is the transfer of kinetic energy between the ocean and the atmosphere and, as such, is an important part of the atmosphere-ocean coupled system. Wind work is defined as the scalar product of ocean wind stress and surface current, with each of t... |
