Description
Using data from observing seasons 1977 through 1984, an analysis of the low l, high n p-mode solar spectra is made with a 0.9 μHz resolution. Frequencies and amplitudes of modes of l < 3 and 11 < n < 33 are determined for each observing season. No clear variation of the frequencies at the 1 μHz level is found and the amplitudes remain constant to ˜ 20%. The frequency spacings between different modes are compared over the solar cycle, as are the constants in Tassoul's asymptotic formula evaluated for each season: no conclusive variations are found.

    An ultra-short-period super-Earth with an extremely high density and an outer companion
    We present the discovery and characterization of a new multi-planetary system around the Sun-like star K2-360 (EPIC 201595106). K2-360 was first identified in K2 photometry as the host of an ultra-short-period (USP) planet candidate with a period of 0.88 d. We obtained follow-up transit photometry, confirming the star as the host of the signal

    Neural calibration of imaging Stokes polarimeters
    Current polarimetric calibration techniques derive the instrument modulation matrix by numerically fitting an instrumental model to measurements of a set of calibration Stokes vectors. These techniques are typically limited to an error on the retrieved normalized Stokes Q, U and V parameters, in the $1\times10^{-2}$ to $1\times10^{-3}$ range. This

    CEERS Key Paper. IX. Identifying Galaxy Mergers in CEERS NIRCam Images Using Random Forests and Convolutional Neural Networks
    A crucial yet challenging task in galaxy evolution studies is the identification of distant merging galaxies, a task that suffers from a variety of issues ranging from telescope sensitivities and limitations to the inherently chaotic morphologies of young galaxies. In this paper, we use random forests and convolutional neural networks to identify
