The effect of the ionosphere on astronomical observations below 100 MHz by De Gasperin, F., Mevius, M., Intema, Hubertus

“…We derive the expected systematic error induced by the ionosphere on radio astronomical observations at low frequencies. We compare our predictions with data from the Low Frequency Array (LOFAR). …”

Laboratory spectroscopy and astronomical significance of the fully-benzenoid PAH triphenylene and its cation by Kofman, V., Sarre, Peter, Hibbins, R.E., ten Kate, I.L., Linnartz, H.

“…Based on the argon-matrix experimental results, comparison is made with previously unpublished astronomical spectra near 400 nm which contain broad interstellar absorption features consistent with the predictions from the laboratory matrix spectra, thus providing motivation for the recording of gas-phase electronic spectra of the internally cold triphenylene cation.…”

Astronomical constraints on the duration of the Early Jurassic Pliensbachian Stage and global climatic fluctuations by Ruhl, Micha, Hesselbo, Stephen P., Hinnov, Linda, Jenkyns, Hugh C., Xu, Weimu, Riding, James B., Storm, Marisa S., Minisini, Daniel, Ullmann, Clemens V., Leng, Melanie J.

“…Here, we show that the Pliensbachian Stage and the Sinemurian–Pliensbachian global carbon-cycle perturbation (marked by a negative shift in δ13Cδ13C of 2–4‰2–4‰), have respective durations of ∼8.7 and ∼2 Myr. We astronomically tune the floating Pliensbachian time scale to the 405 Kyr eccentricity solution (La2010d), and propose a revised Early Jurassic time scale with a significantly shortened Sinemurian Stage duration of 6.9±0.4 Myr6.9±0.4 Myr. …”
