One replicate of each of three makes of vacuum pumps and three replicates of each of nine makes of pulsators were performance tested over a period of 2000 hr. Capacity, faults and breakdowns were ...

We present results from our Chandra and XMM–Newton observations of two low-luminosity X-ray pulsators SAX J1324.4−6200 and SAX J1452.8−5949 which have spin periods of 172 and 437 s, respectively. The ...

We consider the case of beta Cephei pulsators and, with the aim of estimating quantitatively how the available observational constraints determine the type and precision of our inferences, we set the ...

In conclusion, these pulsators currently represent a challenge for both evolutionary and pulsation models, and additional data are needed to increase the number of known ULPs and improve the coverage ...

There has been substantial development in the correct way to treat parameter correlations and degeneracies for asteroseismology of g-mode pulsators by moving away from the often-used χ 2 merit ...

The dairy cows at Heavenly Acres Farm in Stanardsville are living the sweet life.For about 50 heifers, they stay out of direct sun and in a barn. Their stalls, lined ...
