Pursuant to \u00a77 (1) and (3) of Resolution No. 61\/X\/2022 of the Senate of the Jagiellonian University of 26 October 2022 on the terms and conditions for admission to the Doctoral School of Exact and Natural Sciences at the Jagiellonian University in the academic year 2023\/2024, the Director of the Doctoral School of Exact and Natural Sciences announces an\u00a0<\/span>additional opening in the Doctoral School (2 positions)<\/strong>\u00a0<\/span>within the\u00a0<\/span>Astronomy\u00a0<\/span><\/strong>education program, with\u00a0<\/span>employment\u00a0<\/span><\/strong>funded through the research project of the\u00a0<\/span>European Research Council (ERC)<\/strong>\u00a0<\/span>titled \u201cHydrogen and deuterium survey of minor bodies: transformative science with a purpose-built CubeSat<\/a><\/strong>\u201d (101089312 HYADES). The project leader,\u00a0<\/span>Dr. Micha\u0142 Drahus<\/a><\/strong>\u00a0<\/span>(Institute –\u00a0<\/span>Astronomical Observatory<\/a>,\u00a0<\/span>Faculty of Physics, Astronomy, and Applied Computer Science<\/a>, Jagiellonian University), offers the opportunity to pursue a doctoral degree related to the project\u2019s theme.<\/p>\n

This is an offer of education in doctoral school\u00a0<\/span>combined with employment<\/strong>\u00a0funded by a European Research Council (ERC) grant.<\/div>\n

Description of the research project:<\/span><\/p>\n

The advent of standardized small satellites called CubeSats has made astronomical research from space more accessible than ever before. The HYADES project directly derives from the vast research possibilities offered by this platform, and aims at the construction of a miniature UV space telescope designed specifically to detect hydrogen and deuterium around comets and asteroids through the ultra-luminous Lyman alpha transition. Thanks to the unparalleled sensitivity to these atoms, the envisioned satellite will provide definite answers to some of the most profound problems of the near Universe.<\/p>\n

First, it will enable ultra-sensitive searches for hydrogen clouds around future interstellar objects passing through the Solar System, with direct implications to our understanding of orbital anomalies in the absence of visible dust (such as observed in \u2018Oumuamua), as well as physical nature of these bodies in general.<\/p>\n

Second, the satellite will allow for deep investigation of hydrogen content around main-belt comets, probing water-ice outgassing from these bodies. The high level of sensitivity will be routinely achieved for all known objects of this class, including new main-belt comets discovered by LSST, transforming our knowledge of the ice reservoir in the outer Main Belt.<\/p>\n

Finally, the satellite will provide homogeneous, model-independent and self-consistent measurements of the D\/H ratio for dozens of comets from different dynamical classes down to 12 mag of total brightness, which is a factor-of-hundred improvement in sensitivity over the state-of-the-art methods and a major leap in measurement reliability. The D\/H measurements will ultimately resolve the puzzle of cometary origin of water on Earth and unveil the link between present-day cometary reservoirs and their original place of formation in the solar nebula.<\/p>\n
