Astrometry in the 1960s and 1970s was still entirely ground-based, and all too often seen
(and experienced by very few) as a rather tedious, time-consuming technique that no longer …

We present a comprehensive analysis of the properties of the pulsating δ Scuti and related
variables based mainly on the content of the recently published catalogue by Rodríguez et …

The relations between liigheamplitude a Scuti stars and the much more abundant
lOWWaIlelllee 6 Sat variables are not clear. Both groups have similar periods and seem to …

We present 35 new pulsating DA (hydrogen atmosphere) white dwarf stars discovered from
the Sloan Digital Sky Survey (SDSS) and the Hamburg Quasar Survey (HQS). We have …

We present the observed pulsation spectra of all known noninteracting ZZ Ceti stars
(hydrogen atmosphere white dwarf variables [DAVs]) and examine changes in their …

Aims. To date, WASP-33 is the only δ Scuti star known to be orbited by a hot Jupiter. The
pronounced stellar pulsations, showing periods comparable to the primary transit duration …

ABSTRACT The Optical Gravitational Lensing Experiment (OGLE) data on high‐amplitude δ
Scuti stars (HADS) and RR Lyrae stars have been analyzed to determine the distance to the …

We have carried out an intensive survey of the northern region of the Fornax dwarf
spheroidal galaxy with the aim of detecting the galaxy's short-period pulsating stars (P< 0.25 …

We present a detailed linear, nonadiabatic pulsational scenario for oscillating blue
stragglers (BSs)/SX Phe variables in Galactic globular clusters (GGCs) and in Local Group …

We present CCD photometry of SX Phe variables in the field of the globular cluster M 55. We
have discovered 27 variables, three of which are probable members of the Sagittarius dwarf …
