WD 1145+017 is the first white dwarf known to be orbited by disintegrating exoasteroids. It is a helium-dominated white dwarf with lines of metals in spectra and variable asymmetric transits. The analysis of WD 1145 light curve allowed us to identify at least 8 bodies which periodically eclipse the star, showing periods ranging from 4.490 to 4.493 hours. Waterfall diagram shows that some of these periods are not stable. Estimating transit depths gave us possibility to assess the disintegration rate. We have estimated the lower limit of dust masses associated with these bodies, which exhibits time-varying characteristics, fluctuating within the range of approximately 2 − 3 × 10 14 kg.","PeriodicalId":515045,"journal":{"name":"Contributions of the Astronomical Observatory Skalnaté Pleso","volume":"132 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140470495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this contribution I summarize the main characteristics and effects that are observed during outbursts of symbiotic stars: properties of the hot-and warm-type outbursts, enhanced mass outflow occasionally followed by ejection of bipolar jets, and the emergence of a neutral near-orbital-plane region. The results presented were largely obtained using small telescopes, supplemented by observations from the archives of terrestrial and space observatories","PeriodicalId":515045,"journal":{"name":"Contributions of the Astronomical Observatory Skalnaté Pleso","volume":"1147 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140466905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fast sub-second optical variability exists in some important classes of astrophysical sources, in particular pulsars and X-ray binaries. We regularly perform ultra-fast optical photometric campaigns on some of the most interesting targets and transient events. At the same time, we are tackling new campaigns searching for fast optical variability in other types of sources (Fast Radio Bursts, magnetars). To this end we use and develop dedicated fast photon counting instrumentation in the visible band, an area in which our team is the leader. Observations are carried out within the framework of multiwave-length campaigns and in synergy with facilities operating at other wavelengths. Here we report on some of the most recent observing campaigns and technological developments, and on the outcome of a km-baseline experiment of stellar intensity interferometry carried out in photon counting mode.","PeriodicalId":515045,"journal":{"name":"Contributions of the Astronomical Observatory Skalnaté Pleso","volume":"1217 46","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140467111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Optical Gravitational Lensing Experiment (OGLE) is one of the most extensive sky surveys on a global scale. It focuses on optical astrophysical variability and is carried out using the dedicated 1.3-meter Warsaw Telescope located at Las Campanas Observatory in Chile. Since 1992, the OGLE project has been continuously observing the densest regions of the southern sky, namely, the Galactic bulge, Galactic disk, and Magellanic Clouds. To date, the survey has collected over a trillion individual photometric observations for approximately two billion stars. Throughout its long history, the OGLE project has yielded significant contributions to various fields of astrophysics, including gravitational lensing and microlensing, dark matter, exoplanets, variable stars, the structure of the Milky Way and other galaxies, and more. This article presents the most significant achievements of OGLE over the past 30 years.","PeriodicalId":515045,"journal":{"name":"Contributions of the Astronomical Observatory Skalnaté Pleso","volume":"35 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140463482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
