  • Galactic pane infrared polarization survey (GPIPS): Data Release 4 

    Clemens, D. P.; Cashman, Lauren; Cerny, Catherine; El-Batal, Adham; Jameson, Katherine; Marchwinski, R.; Montgomery, Jordan; Pavel, M.; Pinnick, A.; Taylor, B. (American Astronomical Society, 2020-07-29)
    The Galactic Plane Infrared Polarization Survey (GPIPS) seeks to characterize the magnetic field in the dusty Galactic disk using near-infrared stellar polarimetry. All GPIPS observations were completed using the 1.83 m ...
  • Probing interstellar grain growth through polarimetry in the Taurus cloud complex 

    Vaillancourt, John E.; Andersson, B.-G.; Clemens, Dan P.; Piirola, Vilppu; Hoang, Thiem; Becklin, Eric E.; Caputo, Miranda (American Astronomical Society, 2020-12-23)
    The optical and near-infrared (OIR) polarization of starlight is typically understood to arise from the dichroic extinction of that light by dust grains whose axes are aligned with respect to a local magnetic field. The ...
  • Multiwavelength polarimetry of the filamentary cloud IC 5146. II. Magnetic field structures 

    Wang, Jia-Wei; Lai, Shih-Ping; Clemens, Dan P.; Koch, Patrick M.; Eswaraiah, Chakali; Chen, Wen-Ping; Pandey, Anil K. (American Astronomical Society, 2020-01-01)
    The IC 5146 cloud is a nearby star-forming region in Cygnus, consisting of molecular gas filaments in a variety of evolutionary stages. We used optical and near-infrared polarization data toward the IC 5146 cloud, reported ...
  • Magnetized filamentary gas flows feeding the young embedded cluster in Serpens South 

    Pillai, Thushara G. S.; Clemens, Dan P.; Reissl, Stefan; Myers, Philip C.; Kauffmann, Jens; Lopez-Rodriguez, Enrique; Alves, F. O.; Franco, G. A. P.; Henshaw, Jonathan; Menten, Karl M.; Nakamura, Fumitaka; Seifried, Daniel; Sugitani, Koji; Wiesemeyer, Helmut (Springer Science and Business Media LLC, 2020-12)
    Observations indicate that molecular clouds are strongly magnetized, and that magnetic fields influence the formation of stars. A key observation supporting the conclusion that molecular clouds are significantly magnetized ...
  • The first habitable-zone Earth-sized planet from TESS. II. Spitzer confirms TOI-700 d 

    Rodriguez, Joseph E.; Vanderburg, Andrew; Zieba, Sebastian; Kreidberg, Laura; Morley, Caroline V.; Eastman, Jason D.; Kane, Stephen R.; Spencer, Alton; Quinn, Samuel N.; Cloutier, Ryan; Huang, Chelsea X.; Collins, Karen A.; Mann, Andrew W.; Gilbert, Emily; Schlieder, Joshua E.; Quintana, Elisa V.; Barclay, Thomas; Suissa, Gabrielle; Kopparapu, Ravi Kumar; Dressing, Courtney D.; Ricker, George R.; Vanderspek, Roland K.; Latham, David W.; Seager, Sara; Winn, Joshua N.; Jenkins, Jon M.; Berta-Thompson, Zachory; Boyd, Patricia T.; Charbonneau, David; Caldwell, Douglas A.; Chiang, Eugene; Christiansen, Jessie L.; Ciardi, David R.; Colón, Knicole D.; Doty, John; Gan, Tianjun; Guerrero, Natalia; Günther, Maximilian N.; Lee, Eve J.; Levine, Alan M.; Lopez, Eric; Muirhead, Philip S.; Newton, Elisabeth; Rose, Mark E.; Twicken, Joseph D.; Villaseñor, Jesus Noel (American Astronomical Society, 2020-08-14)
    We present Spitzer 4.5 μm observations of the transit of TOI-700 d, a habitable-zone Earth-sized planet in a multiplanet system transiting a nearby M-dwarf star (TIC 150428135, 2MASS J06282325–6534456). TOI-700 d has a ...
  • GJ 1252 b: A 1.2 R ⊕ planet transiting an M3 dwarf at 20.4 pc 

    Shporer, Avi; Collins, Karen A.; Astudillo-Defru, Nicola; Irwin, Jonathan; Bonfils, Xavier; Collins, Kevin I.; Matthews, Elisabeth; Winters, Jennifer G.; Anderson, David R.; Armstrong, James D.; Charbonneau, David; Cloutier, Ryan; Daylan, Tansu; Gan, Tianjun; Günther, Maximilian N.; Hellier, Coel; Horne, Keith; Huang, Chelsea X.; Jensen, Eric L. N.; Kielkopf, John; Palle, Enric; Sefako, Ramotholo; Stassun, Keivan G.; Tan, Thiam-Guan; Vanderburg, Andrew; Ricker, George R.; Latham, David W.; Vanderspek, Roland; Seager, Sara; Winn, Joshua N.; Jenkins, Jon M.; Colon, Knicole; Dressing, Courtney D.; Léepine, Sébastien; Muirhead, Philip S.; Rose, Mark E.; Twicken, Joseph D.; Villasenor, Jesus Noel
    We report the discovery of GJ 1252 b, a planet with a radius of 1.193 ± 0.074 R⊕ and an orbital period of 0.52 days around an M3-type star (0.381 ± 0.019 M⊙, 0.391 ± 0.020 R⊙) located 20.385 ± 0.019 pc away. We use TESS ...
  • Satellite galaxies in the Illustris-1 simulation: anisotropic locations around relatively isolated hosts 

    Brainerd, Tereasa G.; Yamamoto, Masaya (Oxford University Press (OUP), 2019-10-11)
    We investigate the locations of satellite galaxies in the z = 0 redshift slice of the hydrodynamical Illustris-1 simulation. As expected from previous work, the satellites are distributed anisotropically in the plane of ...
  • A small and round heliosphere suggested by MHD modeling of pick-up ions 

    Opher, Merav; Loeb, Abraham; Drake, James; Toth, Gabor (Nature Research, 2020-03-16)
    As the Sun moves through the surrounding partially-ionized medium, neutral hydrogen atoms penetrate the heliosphere, and through charge-exchange with the supersonic solar wind, create a population of hot pick-up ions (PUIs). ...
  • Major scientific challenges and opportunities in understanding magnetic reconnection and related explosive phenomena throughout the universe 

    Ji, Hantao; Alt, A.; Antiochos, S.; Opher, Merav (2019-05-01)
    This is a group white paper of 100 authors (each with explicit permission via email) from 51 institutions on the topic of magnetic reconnection which is relevant to 6 thematic areas. Grand challenges and research opportunities ...
  • Coronal disturbances and their effects on the dynamics of the heliosphere 

    Provornikova, Elena; Merkin, Vyacheslav; Opher, Merav; Richardson, John; Izmodenov, Vladislav; Brandt, Pontus; McNutt, Ralph (2019-09-01)
    The Sun blows out the solar wind which propagates into the interplanetary medium and forms the heliosphere about 100 AU across. The solar activity causes various types of time-dependent phenomena in the solar wind from ...
