Main sequence stars masquerading as young stellar objects in the central molecular zone
... whether main-sequence stars (Stage 2+) embedded in an ambient density medium could mimic deeply embedded YSOs (Stage 0/1) and match the measured brightness profile of the real observation in MIPS 24 μm, we ...

Magnetic fields and X ray emission in pre main sequence stars
... The final case of taking into account the finite resolution limitation on observational re- constructions of surface magnetic fields has a simplifying effect on the extrapolated field. This suggests that the resolution ...

14 new eclipsing white dwarf plus main-sequence binaries from the SDSS and Catalina surveys
... Two of the close binaries listed in Table 3 have slightly odd light curves, which are shown in Figure 7. In both cases there is a sinusoidal variation on half the orbital period, similar to el- lipsoidal modulation, but ...

Binary star influence on post main sequence multi planet stability
... Here, we address the dearth of work investigating cir- cumstellar planetary systems within evolved binaries by es- timating a stability limit for a relatively simple but im- portant base case. We consider two nearly ...

Discovery of ZZ Cetis in detached white dwarf plus main-sequence binaries
... We present the first results of a dedicated search for pulsating white dwarfs (WDs) in detached white dwarf plus main-sequence binaries. Candidate systems were selected from a catalogue of WD+MS binaries, ...

Magnetic fields and differential rotation on the pre-main sequence - III. The early-G star HD 106506
... We present photometry and spectropolarimetry of the pre-main sequence star HD 106506. A photometric rotational period of ∼ 1.416 ± 0.133 days has been de- rived using observations at Mount Kent Observatory ...

ALMA and Herschel reveal that AGN and main-sequence galaxies have different star formation rate distributions
... by providing an obscuration-independent view of star-formation that is largely uncontaminated by emission from the AGN. How- ever, with even the deepest Herschel surveys detecting . 50 per cent of the AGN population, ...

An M Dwarf Companion to an F-type Star in a Young Main-sequence Binary
... Only a few well characterized very low-mass M dwarfs are known today. Our understanding of M dwarfs is vital as these are the most common stars in our solar neighborhood. We aim to characterize the properties of a rare F ...

The open flux evolution of a solar mass star on the main sequence
... In order to constrain our model, we use the rotation periods of stars in open clusters of known ages. Since we are studying rotation period evolution on the main sequence, we have chosen clusters that have ...

The age–metallicity relation in the solar neighbourhood from a pilot sample of white dwarf–main sequence binaries
