Ez a lepes a legalabb egy TEP-et tartalmazo tobbszoros bolygorendszerek felfedezese es analizise. Az ilyen iranyu koncentralt kutatasaink a HATNet es WHAT automata tavcso projektjeink altal szolgaltatott, es folyamatosan bovulu adatbazison, valamint a nagy tavcsovekkel kapott nagypontossagu radialis sebesseg meresekre fog tamaszkodni. A tobbszoros bolygorendszerek felfedezese resze lesz a rendszeres TEP felfedezo es analizalo programunknak. A palyazatban foglaltak varhatoan sikeres vegrahajtasara a HATNet projektnek a TEP kutatasban betoltott jelentos szerepe es a HAT-P-13b, az elso, bolygorendszerben talalhato TEP felfedezese utal. Az ilyen tipusu rendszerek analizise lehetove teszi szamunkra a bolygok belso szerkezetenek sokkal reszletesebb vizsgalatat (mint ahogy az az egyszeres rendszerek eseteben teheto), valamit tovabbi eros megszoritasokat ad a bolygorendszer keletkezesere es fejlodesere vonatkozoan. A tervezett teleszkop hardver es az adatkezelest valamint analizist tamogato szamitastechnikai fejlesztesekkel a projekt fontos infrastrukturalis hatassal lesz a kutatoi kornyezetre.

Summary
The planned research targeted by this proposal attempts to reach the next important step in transiting extrasolar planet (TEP) research by discovering and analyzing multiplanetary systems with at least one transiting component. In conducting this concentrated effort we rely on the continuously extending photometric database of our automated telescope projects HATNet and WHAT and on high-precision radial velocity measurements obtained through telescope times allocated at large-aperture telescopes. The discovery of the multiplanetary systems will be part of our regular search and analysis of extrasolar planets. The expected success of the project is implied by the very significant role of HATNet in the TEP research and the discovery of HAT-P-13b, the first TEP in a planetary system. Analysis of this type of systems enables us to study the internal structures of planets in far more details than in the case of the single planet systems. They also put strong constraints on planetary system formation and evolution. With the planned developments concerning telescope hardware and computer support for data handling and analysis, the project introduces important infrastructural changes in the research environment. The employment of young researchers helps in training new scientists.

Results in English
From the continuous search in the photometric database accumulated by HATNet, during the past four years we have discovered 34 extrasolar planetary systems showing periodic dimming of the host stars by their transiting companion planets. The orbital periods, the planet masses and radii, respectively, span the ranges of 1.2-11 days, 19-2300 M_Earth and 9-20 R_Earth. We detected at least 2 systems with a second planet, based on the wobble of the host stars visible in their radial velocity variations. These systems consist of a short-period transiting planet and another one with several Jupiter masses at a very long period outer orbit. In a side project we utilized our photometric time series to investigate the stellar variability in open clusters. We discovered a large number of rotational variables in two well-known clusters (Pleiades and Praesepe) and thereby increased the number of known rotation periods in these clusters by factors of 5 and 3, respectively. These variables follow fairly tight relations between their colors and rotation periods and enable us to estimate relative stellar ages with high precision.
