Underage parenting is an experience that can be defined as difficult, even critical. It is the same both for teenagers and their families. Adopting the role of a father and mother in adolescence, and so prematurely, generates a number of difficulties that occur in almost every sphere of functioning of these young people. It is therefore necessary to take steps supporting not only underage parents, but also their families. In this article, the issue of supporting teen parents and their families have been described. The sources of information are the empirical studies of underage mothers carried out in 2008 and underage fathers in 2012-2013. They enabled not only to recognize the difficulties that usually involve teen parents, but also the scope and type of support they receive

Absolute properties of the main-sequence eclipsing binary FM Leo
First spectroscopic and new photometric observations of the eclipsing binary
FM Leo are presented. The main aims were to determine orbital and stellar
parameters of two components and their evolutionary stage. First spectroscopic
observations of the system were obtained with DDO and PST spectrographs. The
results of the orbital solution from radial velocity curves are combined with
those derived from the light-curve analysis (ASAS-3 photometry and
supplementary observations of eclipses with 1 m and 0.35 m telescopes) to
derive orbital and stellar parameters. JKTEBOP, Wilson-Devinney binary
modelling codes and a two-dimensional cross-correlation (TODCOR) method were
applied for the analysis. We find the masses to be M_1 = 1.318 0.007 and
M_2 = 1.287 0.007 M_sun, the radii to be R_1 = 1.648 0.043 and R_2
= 1.511 0.049 R_sun for primary and secondary stars, respectively. The
evolutionary stage of the system is briefly discussed by comparing physical
parameters with current stellar evolution models. We find the components are
located at the main sequence, with an age of about 3 Gyr.Comment: 5 pages, 4 figures, to appear in MNRA
Underage Parents and Their Families as a Subject of Support. Independent Research
Underage parenting is an experience that can be defined as difficult, even critical. It is the same both for teenagers and their families. Adopting the role of a father and mother in adolescence, and so prematurely,
generates a number of difficulties that occur in almost every sphere of functioning of these young people. It is therefore necessary to take steps supporting not only underage parents, but also their families. In this
article, the issue of supporting teen parents and their families have been described. The sources of information are the empirical studies of underage mothers carried out in 2008 and underage fathers in 2012-2013. They enabled not only to recognize the difficulties that usually involve teen parents, but also the scope and type of support they receive.118920211Kultura-Społeczeństwo-Edukacj
Orbital and physical parameters of eclipsing binaries from the ASAS catalogue -- III. Two new low-mass systems with rapidly evolving spots
We present the results of our spectroscopic and photometric analysis of two
newly discovered low-mass detached eclipsing binaries found in the All-Sky
Automated Survey (ASAS) catalogue: ASAS J093814-0104.4 and ASAS J212954-5620.1.
Using the GIRAFFE instrument on the 1.9-m Radcliffe telescope at SAAO and the
UCLES spectrograph on the 3.9-m Anglo-Australian Telescope, we obtained
high-resolution spectra of both objects and derived their radial velocities
(RVs) at various orbital phases. The RVs of both objects were measured with the
TODCOR technique using synthetic template spectra as references. We also
obtained V and I band photometry using the 1.0-m Elizabeth telescope at SAAO
and the 0.4-m PROMPT instruments located at the CTIO. The orbital and physical
parameters of the systems were derived with PHOEBE and JKTEBOP codes. We
compared our results with several sets of widely-used isochrones. Our
multi-epoch photometric observations demonstrate that both objects show
significant out-of-eclipse modulations, which vary in time. We believe that
this effect is caused by stellar spots, which evolve on time scales of tens of
days. For this reason, we constructed our models on the basis of photometric
observations spanning short time scales (less than a month). Our modeling
indicates that (1) ASAS-09 is a main sequence active system with nearly-twin
components with masses of M1 = 0.771(33) Msun, M2 = 0.768(21) Msun and radii of
R1 = 0.772(12) Rsun and R2 = 0.769(13) Rsun. (2) ASAS-21 is a main sequence
active binary with component masses of M1 = 0.833(17) Msun, M2 = 0.703(13) Msun
and radii of R1 = 0.845(12) Rsun and R2 = 0.718(17) Rsun. Both systems confirm
the characteristic of active low-mass stars, for which the observed radii are
larger and the temperatures lower than predicted by evolutionary models. Other
parameters agree within errors with the models of main sequence stars.Comment: 15 pages, 7 figures, 7 tables, to appear in A&
