Doppler-Shifted Alkali D Absorption as Indirect Evidence for Exomoons by Carl A. Schmidt

“…The Doppler shift also aids in isolating the planetary signature from the stellar photosphere’s absorption. Only one transiting exoplanet, HD 80606b, is presently thought to have both this requisite Doppler shift and alkali absorption. …”

The X-Ray Evolution of the Symbiotic Star V407 Cyg During its 2010 Outburst by Mukai K., Nelson T., Chomiuk L., Donato D., Sokoloski J.

“…We identify this as the time when the blast wave reached the immediate vicinity of the photosphere of the Mira. We have developed a simpe model of the blast wave - wind interaction that can reproduce the gross features of the X-ray evolution of V407 Cyg. …”

The Type II-plateau Supernova 2017eaw in NGC 6946 and Its Red Supergiant Progenitor by Crossfield, Ian Jm

“…The distances to the SN that we have also estimated via both the standardized candle method and expanding photosphere method corroborate the TRGB distance. We confirm the SN progenitor identity in pre-explosion archival Hubble Space Telescope (HST) and Spitzer Space Telescope images, via imaging of the SN through our HST Target of Opportunity program. …”

Atmospheric circulation of hot Jupiters: dayside–nightside temperature differences. II. Comparison with observations by Komacek, T, Showman, A, Tan, X

“…We interpret this as being due to the effects of a process that moves the infrared photospheres of these cooler hot Jupiters to lower pressures. …”

Deep fracture fluids isolated in the crust since the Precambrian era. by Holland, G, Lollar, B, Li, L, Lacrampe-Couloume, G, Slater, G, Ballentine, C

“…In one such system, 2.8 kilometres below the surface in a South African gold mine, extant chemoautotrophic microbes have been identified in fluids isolated from the photosphere on timescales of tens of millions of years. …”

Magnetic reconnection processes induced by a CME expansion by A. Bemporad, A. Bemporad, G. Poletto, F. Landini, M. Romoli

Effects of Partial Ionization on Magnetic Flux Emergence in the Sun by Georgios Chouliaras, P. Syntelis, V. Archontis

“…The expansion of the field above the photosphere occurs relatively earlier in the PI case, and we confirm that the inclusion of partial ionization reduces cooling due to adiabatic expansion. …”

Temporal Variation of the Rotation in the Solar Transition Region by Xiaojuan Zhang, Linhua Deng, Yu Fei, Chun Li, Xinan Tian

“…The temporal variations of solar rotation in the photosphere, chromosphere, and corona have been widely investigated, whereas the rotation of the solar transition region is rarely studied. …”

ANOMALOUS WIDENING OF 5434.5 LINE IN SUNSPOTS: SUPER-STRONG MAGNETIC FIELDS? by V. G. Lozitsky, S. M. Osipov, M. I. Stodilka

“…A semi-empirical model constructed for the first sunspot by FeI 5434.5 line using inverse code with Tikhonov`s stabilizers shows an anomalous feature – the maximum of microturbulent velocities in the upper photosphere and the temperature minimum zone instead of the usual small increase of microturbulence at these heights. …”

Solar Surface Magneto-Convection by Robert F. Stein

“…We review the properties of solar magneto-convection in the top half of the convection zones scale heights (from 20 Mm below the visible surface to the surface, and then through the photosphere to the temperature minimum). Convection is a highly non-linear and non-local process, so it is best studied by numerical simulations. …”

Polarimetric Evidence of the First White Dwarf Pulsar: The Binary System AR Scorpii by David A.H. Buckley, Stephen B. Potter, Pieter J. Meintjes, Tom R. Marsh, Boris T. Gänsicke

“…These observations, coupled with the spectral energy distribution (SED) which is dominated by non-thermal emission, characteristic of synchrotron emission, support the notion that a strongly magnetic (∼200 MG) white dwarf is behaving like a pulsar, whose magnetic field interacts with the secondary star’s photosphere and magnetosphere. Radio synchrotron emission is produced from the pumping action of the white dwarf’s magnetic field on coronal loops from the M-star companion, while emission at high frequencies (UV/optical/X-ray) comes from the particle wind, driven by large electric potential, again reminiscent of processes seen in neutron star pulsars.…”

Fermi Constraints on the Ejecta Speed and Prompt Emission Region of the Distant GRB 220101A by Lorenzo Scotton, Frédéric Piron, Nicola Omodei, Niccolò Di Lalla, Elisabetta Bissaldi

“…Regardless of the nature of the emission processes assumed in the spectral analysis, we infer a moderate value for the jet Lorentz factor, Γ ∼ 110, and find that all of the high-energy emission was produced above and near the photosphere, at a distance of ∼10 ^14 cm from the central engine. …”
