    Observation of tantalum deposition and growth on TiB2 and ZrB2 from PISCES-RF deuterium and helium plasma exposures by L. Nuckols, C.M. Parish, M.J. Baldwin, H.M. Meyer, III, D. Nishijima, M.I. Patino, J. Rapp

    Published 2024-06-01
    “…Deuterium and helium plasma exposures on bulk TiB2 and ZrB2 samples were performed using the PISCES-RF linear plasma device. 40 and 90 eV deuterium ion plasma exposures were performed at 240 and 800 °C sample temperatures, and 80 eV helium ion plasma exposures were performed at 800 °C sample temperatures. …”

    A Comparative Study between M30 and M92: M92 is a Merger Remnant with a Large Helium Enhancement by Jae-Woo Lee

    Published 2024-01-01
    “…We also find that the metal-rich group of stars in M92 shows a helium enhancement as large as Δ Y ∼ 0.05 from the red giant branch bump V magnitudes, which can also be supported by (i) a lack of bright red giant branch stars, (ii) synthetic evolutionary horizontal branch population models and (iii) the more extended spatial distribution due to different degree of the diffusion process from their lower masses. …”
