Search for pulsation among suspected A-type binaries and the new multiperiodic Delta Scuti star HD217860
Yves Fremat, P. Lampens, P. Van Cauteren +9
We have explored a sample of suspected A-type binaries in a systematic way, both spectroscopically and photometrically. Due to their location in the H-R diagram, indications of pul…
The double-mode nature of the HADS star GSC 00144-03031 and the Petersen diagram of the class
E. Poretti, J. C. Suarez, P. G. Niarchos +13
The double--mode pulsation of GSC 00144-03031 has been detected when searching for COROT targets. A very large dataset composed of 4722 photometric measurements was collected at si…
A Photometric Study of the Light Variations of the Triple System DG Leonis
P. Lampens, Y. Frémat, R. Garrido +8
Multi-site and multi-year differential photometry of the triple star DG Leo reveals a complex frequency spectrum that can be modelled as the combination of at least three Delta Scu…
Delta Scuti Stars in Stellar Systems: the interest of HD 220392 and HD 220391
P. Lampens, M. Van Camp
The very wide double star CCDM 23239-5349 is an interesting study case of a pulsating star within a common origin pair or wide binary. Both stars are located in the Delta Scuti ins…
Delta Scuti stars in stellar systems: on the variability of HD 220392 and HD 220391
P. Lampens, M. Van Camp, D. Sinachopoulos
HD 220392 (HR 8895), the brightest member of the visual double star CCDM 23239-5349, is a new short-period variable bright star, probably of the Delta Scuti type. The period analys…
Delta Scuti Stars in Stellar Systems: a Review
P. Lampens, H. M. J. Boffin
We present a list of delta Scuti stars in double and multiple systems, ranging from the very wide binaries to the very close ones such as spectroscopic and eclipsing systems includ…
