Context. In the present-day panorama of large spectroscopic surveys, the amount, diversity, and complexity of the available data continuously increase. The overarching goal of studying the formation and evolution of our Galaxy is hampered by the heterogeneity of instruments, selection functions, analysis methods, and measured quantities. Aims. We present a comprehensive catalogue, the Survey of Surveys (SoS), built by homogeneously merging the radial velocity (RV) determinations of the largest ground-based spectroscopic surveys to date, such as APOGEE, GALAH, Gaia-ESO, RAVE, and LAMOST, using Gaia as a reference. This pilot study serves to prove the concept and to test the methodology that we plan to apply in the future to the stellar parameters and abundance ratios as well. Methods. We have devised a multi-staged procedure that includes: i) the cross match between Gaia and the spectroscopic surveys using the official Gaia cross-match algorithm, ii) the normalisation of uncertainties using repeated measurements or the three-cornered hat method, iii) the cross calibration of the RVs as a function of the main parameters on which depend (magnitude, effective temperature, surface gravity, metallicity, and signal-to-noise ratio) to remove trends and zero point offsets, and iv) the comparison with external high-resolution samples, such as the Gaia RV standards and the Geneva-Copenhagen survey, to validate the homogenisation procedure and to calibrate the RV zero-point of the SoS catalogue. Results. We provide the largest homogenised RV catalogue to date, containing almost 11 million stars, of which about half come exclusively from Gaia and half in combination with the ground-based surveys. We estimate the accuracy of the RV zero-point to be about 0.16-0.31 km s −1 and the RV precision to be in the range 0.05-1.50 km s −1 depending on the type of star and on its survey provenance. We validate the SoS RVs with open clusters from a high resolution homogeneous samples and provide the systemic velocity of 55 individual open clusters. Additionally, we provide median RVs for 532 clusters recently discovered by Gaia data. Conclusions. The SoS is publicly available and ready to be applied to various research projects, such as the study of star clusters, Galactic archaeology, stellar streams, or the characterisation of planet-hosting stars, to name a few. We also plan to include survey updates and more data sources in future versions of the SoS.

“…Several groups have embarked on spectroscopic follow-up of a sample of (typically bright) Kepler EBs. Examples include 20 objects from a set of 75 defined by Hełminiak et al [167][168][169], 43 long-period EBs from K2 campaigns 1-3 for which tidal effects are negligible (Maxted and Hutcheon [170]), and the SDSS-HET survey (Mahadevan et al [171]).…”

Binary stars are crucial laboratories for stellar physics, so have been photometric targets for space missions beginning with the very first orbiting telescope (OAO-2) launched in 1968. This review traces the binary stars observed and the scientific results obtained from the early days of ultraviolet missions (OAO-2, Voyager, ANS, IUE), through a period of diversification (Hipparcos, WIRE, MOST, BRITE), to the current era of large planetary transit surveys (CoRoT, Kepler, TESS). In this time observations have been obtained of detached, semi-detached and contact binaries containing dwarfs, sub-giants, giants, supergiants, white dwarfs, planets, neutron stars and accretion discs. Recent missions have found a huge variety of objects such as pulsating stars in eclipsing binaries, multi-eclipsers, heartbeat stars and binaries hosting transiting planets. Particular attention is paid to eclipsing binaries, because they are staggeringly useful, and to the NASA Transiting Exoplanet Survey Satellite (TESS) because its huge sky coverage enables a wide range of scientific investigations with unprecedented ease. These results are placed into context, future missions are discussed, and a list of important science goals is presented.

ÖzBu çalışmada, Kepler uzay teleskobuyla gözlenen basık yörüngeli ayrık tür KIC 7821010 çift yıldız sisteminin ışık ve ETV eğrilerinin analizleri yapılmıştır. Işık eğrisi ve bileşenlerin dikine hız eğrileri eş zamanlı analiz edilmiş ve elde edilen çözümler ile sistemin mutlak parametreleri hesaplanmıştır. ETV analizi için Python tabanlı iki adet kod yazılmıştır. Bu kodlar kullanılarak Kepler veritabanından alınan ışık eğrilerinden tutulma zamanları hesaplanmış ve ışık zaman etkisiyle birlikte dinamik etki de göz önüne alınarak ETV analizi yapılmıştır. ETV grafiğinde değişime neden olarak sisteme çekimsel olarak bağlı yaklaşık 991 ± 2 gün dönemli ve 2.05 ± 0.06 MJ kütleli üçüncü bir bileşenin varlığı önerilmiştir.
