    Amplifying Resonant Repulsion with Inflated Young Planets, Overlooked Inner Planets, and Nonzero Initial Δ by Yuancheng Xu, Fei Dai

    Published 2025-01-01
    “…Most multiplanet systems around mature (∼5 Gyr old) host stars are nonresonant. Even the near-resonant planet pairs still display 1%–2% positive deviation from perfect period commensurabilities (Δ) near first-order mean motion resonances (MMRs). …”

    SPACE AND TIME EXPRESSIONS IN THE ROMANIAN LINGUISTIC IMAGINARY by Maria-Zoica Eugenia BALABAN

    Published 2023-03-01
    “…We will try to demonstrate that in the Romanian linguistic imaginary there is a vertical spatiality (in terms of an up-down metaphor), which belongs to the pastoral world, in which the archaic man raises his eyes to the sky in a perfect communion with the Divinity (the expressions with sky, earth, sun, moon, stars, etc.). As far as it concerns time, we will inventory those expressions and sayings that reflect, in the collective mind, the time perception between ephemerality and eternity. …”

    Introducing the Condor Array Telescope. V. Deep Broad- and Narrowband Imaging Observations of the M81 Group by Kenneth M. Lanzetta, Stefan Gromoll, Michael M. Shara, David Valls-Gabaud, Frederick M. Walter, John K. Webb

    Published 2025-01-01
    “…We subtracted the luminance image from the narrowband images to leave, more or less, only line emission in the difference images, and we masked regions of the resulting images around stars at an isophotal limit. The difference images exhibit extensive extended structures of ionized gas in the direction of the M81 Group, from known galaxies of the M81 Group, clouds of gas, filamentary structures, and apparent or possible bubbles or shells. …”

    Light Curves of Type IIP Supernovae from Neutrino-driven Explosions of Red Supergiants Obtained by a Semianalytic Approach by Shuai Zha, Bernhard Müller, Amy Weir, Alexander Heger

    Published 2023-01-01
    “…Type IIP supernovae (SNe IIP) mark the explosive death of red supergiants (RSGs), evolved massive stars with an extended hydrogen envelope. They are the most common supernova type and allow for the benchmarking of supernova explosion models by statistical comparison to observed population properties rather than by comparing individual models and events. …”

    “…The final sample is 300 stars (301 including the Sun). The high cosmic abundance of magnesium allowed Mg ii k emissions to be recovered in the warmer F-types, at the edge of convection and chromospheric activity, and in low-activity Sunlike dwarfs—situations in which Ca ii K might be too weak to measure. …”

    Fast Radio Bursts with Narrow Beaming Angles Can Escape from Magnetar Magnetospheres by Yu-Chen Huang, Zi-Gao Dai

    Published 2024-01-01
    “…Growing evidence indicates that at least some FRBs originate from magnetars and are likely generated within the magnetospheres of these highly magnetized neutron stars. However, a recent study suggested that FRBs originating from magnetar magnetospheres would be scattered by magnetospheric electron–positron pair plasma, making it impossible for them to escape successfully. …”
