Tartu Ülikooli Tartu observatooriumil on uus koduleht. Leiate meid aadressilt kosmos.ut.ee.

Annan lühiülevaate peaassamblee programmist, mis sisaldas 7 sümpoosioni, 15 temaatilist nõupidamist ja mitmeid muid üritusi. Tutvustan lähemalt mõnd teadustulemust, näiteks tähe S2 liikumine ümber Linnutee keskme musta augu, Gaia uusimad saavutused jm. Lisandub ka lühiülevaade IAU uutest liikmetest ja funktsionääridest ning 100. aastapäeva tähistamisest.

Francois Bourrin will present his institute CEFREM and his last results on particles characterization using optics acoustics from glider moorings and potential of satellites.

The life of a pulsar born in a binary system has been studied in many ways. The recent proliferation of eclipsing millisecond pulsars, split into two classes called Redbacks and Black Widows, lets us study a variety of pulsars in short orbits around low-mass stars during a pause in the accreting phase and in the post-accreting phase. In addition to studying their evolution, these new systems also allow measurements of the upper range of neutron star masses and give us new ways of studying pulsar winds. But the observational and theoretical challenges are proliferating as fast as the spiders themselves. I will review where we are observationally with these systems, and discuss old and new theoretical challenges.
