  • Chemo-kinematic ages of eccentric-planet-hosting M dwarf stars 

    Veyette, Mark J.; Muirhead, Philip S. (IOP PUBLISHING LTD, 2018-08-20)
    The M dwarf stars are exciting targets for exoplanet investigations; however, their fundamental stellar properties are difficult to measure. Perhaps the most challenging property is stellar age. Once on the main sequence, ...
  • The TESS Input Catalog and Candidate Target List 

    Stassun, Keivan G.; Oelkers, Ryan J.; Pepper, Joshua; Paegert, Martin; De Lee, Nathan; Torres, Guillermo; Latham, David W.; Charpinet, Stephane; Dressing, Courtney D.; Huber, Daniel; Kane, Stephen R.; Lepine, Sebastien; Mann, Andrew; Muirhead, Philip S.; Rojas-Ayala, Barbara; Silvotti, Roberto; Fleming, Scott W.; Levine, Al; Plavchan, Peter (IOP PUBLISHING LTD, 2018-09-01)
    The Transiting Exoplanet Survey Satellite (TESS) will be conducting a nearly all-sky photometric survey over two years, with a core mission goal to discover small transiting exoplanets orbiting nearby bright stars. It will ...
  • Magnetic field uniformity across the GF 9-2 YSO, L1082C dense core, and GF 9 filamentary dark cloud 

    Clemens, Dan P.; El-Batal, A.M.; Cerny, C.; Kressy, S.; Schroeder, G.; Pillai, T. (IOP PUBLISHING LTD, 2018-11-01)
    The orientation of the magnetic field (B field) in the filamentary dark cloud GF 9 was traced from the periphery of the cloud into the L1082C dense core that contains the low-mass, low-luminosity Class 0 young stellar ...
  • The twist of the draped interstellar magnetic field ahead of the heliopause: a magnetic reconnection driven rotational discontinuity 

    Opher, Merav; Drake, J.F.; Swisdak, M.; Zieger, B.; Toth, G. (Institute of Physics Publishing, 2017-04-10)
    Based on the difference between the orientation of the interstellar B ISM and the solar magnetic fields, there was an expectation that the magnetic field direction would rotate dramatically across the heliopause (HP). ...
  • Voyager 2 solar plasma and magnetic field spectral analysis for intermediate data sparsity 

    Gallana, Luca; Fraternale, Federico; Iovieno, Michele; Fosson, Sophie M.; Magli, Enrico; Opher, Merav; Richardson, John D.; Tordella, Daniela (AMER GEOPHYSICAL UNION, 2016-05-01)
    The Voyager probes are the furthest, still active, spacecraft ever launched from Earth. During their 38 year trip, they have collected data regarding solar wind properties (such as the plasma velocity and magnetic field ...
  • Globally distributed energetic neutral atom maps for the "croissant" heliosphere 

    Kornbleuth, M.; Opher, Merav; Michael, A.T.; Drake, J.F. (IOP PUBLISHING LTD, 2018-10-01)
    A recent study by Opher et al. suggested the heliosphere has a "croissant" shape, where the heliosheath plasma is confined by the toroidal solar magnetic field. The "croissant" heliosphere is in contrast to the classically ...
  • The formation of magnetic depletions and flux annihilation due to reconnection in the heliosheath 

    Drake, J.F.; Swisdak, M.; Opher, Merav; Richardson, J.D. (IOP PUBLISHING LTD, 2017-03-10)
    The misalignment of the solar rotation axis and the magnetic axis of the Sun produces a periodic reversal of the Parker spiral magnetic field and the sectored solar wind. The compression of the sectors is expected to lead ...
  • A predicted small and round heliosphere 

    Opher, Merav; Loeb, Abraham; Drake, James; Toth, Gabor
    The shape of the solar wind bubble within the interstellar medium, the so-called heliosphere, has been explored over six decades(1-7). As the Sun moves through the surrounding partially-ionized medium, neutral hydrogen ...
  • Using foreCAT deflections and rotations to constrain the early evolution of CMEs 

    Kay, C.; Opher, M.; Colaninno, R. C.; Vourlidas, A. (IOP PUBLISHING LTD, 2016-08-10)
    To accurately predict the space weather effects of the impacts of coronal mass ejection (CME) at Earth one must know if and when a CME will impact Earth and the CME parameters upon impact. In 2015 Kay et al. presented ...
  • Probability of CME impact on exoplanets orbiting M dwarfs and solar-like stars 

    Kay, C.; Opher, M.; Kornbleuth, M. (IOP PUBLISHING LTD, 2016-08-01)
    Solar coronal mass ejections (CMEs) produce adverse space weather effects at Earth. Planets in the close habitable zone of magnetically active M dwarfs may experience more extreme space weather than at Earth, including ...
