چکیده
We studied light curves of GJ 1243, YZ CMi, and V374 Peg, observed by TESS for the presence stellar spots flares. One main goals was to model spotted stars estimate number along with their parameters using our original BASSMAN software. The modeled were subtracted from observations increase efficiency flare detection. Flares detected automatically new dedicated software WARPFINDER. estimated two on 1243 mean temperature about 2800$\,$K spottedness varying between $3\%-4\%$ surface Peg a 3000$\,$K 6$\%$ surface. On CMi we found different models separated in time one half year. them is three-spot star 9$\%$ second four-spot 7$\%$ tested whether flares are distributed homogeneously phase if there any correlation distribution For spot anticorrelation shows non-homogeneous

The Ṁ − M relationship in pre - main sequence stars
We examine the recent data and analysis of Natta et al. concerning the accretion rate on to young stars as a function of stellar mass, and conclude that the apparently steep dependence of accretion rate on mass is strongly driven by selection/detection thresholds. We argue that a convincing demonstration of a physical relationship between accretion and stellar mass requires further studies whic...
متن کاملISO Observations of Pre - Main Sequence and Vega - type Stars
I present an overview of the results obtained by the Infrared Space Observatory (ISO) on circumstellar material in pre-main sequence (PMS) stars. Results obtained for embedded YSOs, Herbig Ae/Be systems and T Tauri stars are reviewed and their connection to the disks around Vega-type systems is discussed. Although the gas contents of the PMS environment will also be discussed briefly, this revi...
متن کاملUvbyh Photometry of Main Sequence a Type Stars ?
We present Strr omgren uvby and H photometry for a set of 575 northern main sequence A type stars, most of them belonging to the Hipparcos Input Catalogue, with V from 5 m to 10 m and with known radial velocities. These observations enlarge the catalogue we began to compile some years ago to more than 1500 stars. Our catalogue includes kinematic and astrophysical data for each star. Our future ...
متن کاملThe Pre–Main-Sequence of A-type stars
Young A-type stars in the pre–main-sequence (PMS) evolutionary phase are particularly interesting objects since they cover the mass range (∼1.5-4 M⊙) which is most sensitive to the internal conditions inherited during the protostellar phase. In particular, they undergo a process of thermal relaxation from which they emerge as fully radiative objects contracting towards the main sequence. A-type...
متن کاملMagnetic flux transport on active cool stars and starspot lifetimes
Context. Many rapidly rotating cool stars show signatures of large magnetic regions at all latitudes. Mid-latitude starspots and magnetic regions have characteristic lifetimes of 1 month or less, as indicated by observations using (Zeeman-) Doppler imaging techniques. Aims. We aim to estimate the lifetimes of bipolar magnetic regions and starspots on the surfaces of cool stars. We consider diff...
