A dynamical dichotomy in large binary asteroids

K. Minker, B. Carry, F. Vachier +20

No less than 15% of large (diameter greater than 140 km) asteroids have satellites. The commonly accepted mechanism for their formation is post-impact reaccumulation. However, the…

Doppler confirmation of TESS planet candidate TOI1408.01: grazing transit and likely eccentric orbit

G. A. Galazutdinov, R. V. Baluev, G. Valyavin +16

We report an independent Doppler confirmation of the TESS planet candidate orbiting an F-type main sequence star TOI-1408 located 140 pc away. We present a set of radial velocities…

Massive search of spot- and facula-crossing events in 1598 exoplanetary transit lightcurves

R. V. Baluev, E. N. Sokov, I. A. Sokova +40

We developed a dedicated statistical test for a massive detection of spot- and facula-crossing anomalies in multiple exoplanetary transit lightcurves, based on the frequentist -…

Discovery of a young low-mass brown dwarf transiting a fast-rotating F-type star by the Galactic Plane eXoplanet (GPX) survey

P. Benni, A. Y. Burdanov, V. V. Krushinsky +64

We announce the discovery of GPX-1 b, a transiting brown dwarf with a mass of and a radius of , the first sub-stell…

WASP-4 transit timing variation from a comprehensive set of 129 transits

R. V. Baluev, E. N. Sokov, S. Hoyer +6

We homogeneously reanalyse transit light curves for the WASP-4 b hot Jupiter. This set involved new observations secured in 2019 and nearly all observations mentioned in the…

Homogeneously derived transit timings for 17 exoplanets and reassessed TTV trends for WASP-12 and WASP-4

R. V. Baluev, E. N. Sokov, H. R. A. Jones +34

We homogeneously analyse photometric measurements for transit lightcurves belonging to exoplanet hosts. The photometric data cover years…

Ephemeris refinement of 21 Hot Jupiter exoplanets with high timing uncertainties

M. Mallonn, C. von Essen, E. Herrero +32

Transit events of extrasolar planets offer a wealth of information for planetary characterization. However, for many known targets, the uncertainty of their predicted transit windo…

Results of testing for presence of satellites near 18 Melpomene and 532 Herculina by the speckle-interferometry method

I. A. Sokova, E. N. Sokov, V. V. Dyachenko +2

In this work we present results of searching for satellites near the 18 Melpomene and 532 Herculina asteroids, which were predicted in 1978 from analysis of observations at the occ…

Detection of the Binarity of the Star J1158+4239

M. Yu. Khovritchev, A. M. Kulikova, E. N. Sokov +7

One of the goals of the Pulkovo program of research on stars with large proper motions is to reveal among the low-luminosity stars those that have evidence of binarity. Twelve astr…
