Summary in Hungarian
Pályázatunk cefeidák és RR Lyrae csillagok nemlineáris dinamikai jelenségeinek tanulmányozását célozza a rendkívüli pontosságot és folyamatos megfigyelést biztosító Kepler-űrtávcső fotometriai adatai, spektroszkópiai megfigyelések és a legkorszerűbb numerikus hidrodinamikai szimulációk segítségével. A korábban elérhetetlen folytonosságú, mikromagnitúdó pontosságú adatok új megközelítést jelentenek az évszázados megoldatlan problémák, többek között az RR Lyrae csillagok amplitúdó- és fázismodulációjának, a Blazhko-effektusnak a megértésében, lehetővé teszik strange és nemradiális módusok, valamint ismeretlen rezonanciák kimutatását az említett változócsillagokban. Ezen kívül kitűnő eszközt jelentenek a kettősség pulzációra gyakorolt hatásának vizsgálatára, valamint csillag-, illetve bolygókísérők felfedezésére pulzáló változócsillagok körül. Szabó Róbert vezető szerepet játszik a Kepler Asztroszeizmológiai Tudományos Konzorcium cefeida és RR Lyrae munkacsoportjainak koordinálásában. A jelen pályázat egyrészt az egyedülálló minőségű adatokhoz való exkluzív hozzáférésünkre, másrészt a részt vevő kutatók a csillagpulzáció numerikus modellezésében szerzett több évtizedes tapasztalatára épít. A kettő együttes alkalmazása világszínvonalú hozzájárulást tesz lehetővé az adott tudományterületen.
Summary
We aim at studying the nonlinear dynamics of stellar pulsation in Cepheids and RR Lyrae stars, based on the continuous, ultra-precise Kepler space photometry, spectroscopic observations and state-of-the-art numerical hydrodynamical simulations. The unique, continuously sampled, micromagnitude precision data will shed new light on the century-old unsolved problem, the amplitude and phase modulation of RR Lyrae stars, known as the Blazhko-effect. They allow the unambiguous detection of strange and nonradial modes, as well as new phenomena, such as hitherto unknown resonances in these objects. In addition, Kepler data offer an excellent tool to study the effect of binarity on pulsation and to discover stellar and planetary companions around pulsating variable stars. The principal investigator plays a leading role in the Kepler Asteroseismic Science Consortium Cepheid and RR Lyrae Working Groups. This proposal exploits our exclusive access to data of unprecedented quality and is supported by the team's decades-long experience in numerical modelling of stellar pulsation. This synergy places our research in the forefront of present-day astrophysical studies.




 

Final report

  
Results in Hungarian
A Kepler-űrtávcső négyévnyi folyamatos, ultraprecíz adatait felhasználva RR Lyrae csillagok fényváltozásait elemeztük. Új dinamikai jelenségeket tártunk fel, ezeket hidrodinamikai modellekkel megerősítettük. Az amplitúdó- és fázismoduláció évszázados (Blazskó-)rejtélyére új, az eddigieknél megalapozottabb magyarázatot adtunk. Az RR Lyrae csillagok vizsgálatában kutatócsoportunk nemzetközileg elismert, vezető szerepet vívott ki. Cefeidák fényváltozását vizsgálva a Kepler és a MOST űrtávcsövekkel periódus- és fénygörbealak-ingadozását fedeztünk fel. Egyedülálló, triplán fedő hierarchikus hármas rendszert azonosítottunk (HD 181068) és publikáltunk a Science c. folyóiratban. Felfedeztük az első aszimmetrikus fedési fénymenetet mutató exobolygót (Kepler-13b); a jelenséget a csillag gyors forgásával magyaráztunk. Számos, egyéb, a Keplerrel végzett kutatási területbe bekapcsolódtunk, úgy mint asztroszeizmológia, csillaghalmazok, fedési kettősök, fősorozati és vörös változók, aktív csillagok. A Kepler Asztroszeizmológiai Tudományos Konzorcium (KASC) több munkacsoportját vezettük, és csoportunk rendezte a KASC 5. nemzetközi konferenciáját 2012-ben. Részt vettünk a Kepler második küldetésének (K2) tudományos előkészítésében, számos sikeres távcsőidő-pályázatot írtunk. Bekapcsolódtunk a következő európai űrfotometriai missziók előkészítésébe (CHEOPS, PLATO). Száznál több ismeretterjesztő cikket és több tucatnyi ismeretterjesztő előadást tartottunk csak a Kepler eredményeire alapozva.
Results in English
We analyzed the light variations of RR Lyrae stars using the four-year-long ultra-precise, continuous observations of the Kepler space telescope. We discovered new dynamical phenomena, and modeled them with numerical hydrodynamic simulations. We developed a new explanation for the century-old Blazhko-problem, i.e. the amplitude and phase modulation of RR Lyrae stars. Our team became a renown, world-leading research group in this field. By using the Kepler and MOST space telescopes, we unveiled tiny period and light curve shape variations of Cepheids. We discovered a unique, triply eclipsing hierarchical triple stellar system (HD 181068), and published the results in the Science Magazine. We found the first exoplanet (Kepler-13b) with an asymmetric transit curve, which is caused by the rapid rotation of the host star. We contributed to several Kepler-related research areas, like asteroseismology, stellar clusters, eclipsing binaries, red and main-sequence pulsating variables, and stellar activity. We led several working groups of the Kepler Asteroseismic Science Consortium (KASC), and our group organized the 5th international conference of KASC in 2012. We took part in the scientific preparatory work of the successor mission of Kepler (K2), we have several successful K2 target proposals. We worked on planning future European space photometric missions (CHEOPS, PLATO). We wrote more than 100 popular astronomy papers and gave dozens of talks based on the results of Kepler.
